What secret did you find out by complete accident?

I found out that my stepdad made my mom get rid of my childhood cat by throwing her out of their car window because he was allergic to them. They lied to me and told me that they gave her to a family who really wanted a cat and they had a little girl who was my age at the time. My mom was crying to him because she felt bad about it. Their bedroom door was closed. I ended up coming home early that day so they weren’t expecting me.

That I’m not actually Native American and my great grandfather just spent time on reservations because he was an alcoholic… turns out addiction goes way back in my family lol

While digging through some old pictures at my wife's childhood home I found her grandparent's marriage license. I was reading it and said, " I didn't know Grandpa previously married and divorced.". It was pretty clear by the look on her Dad's face that he didn't know that either.

I found out that my father had an affair with my ex, didn’t see that coming tbh

My brother, his wife, and wife’s best friend left for a trip to visit family during the holidays but I had to stay home due to there being no space and work. I got a phone call from the wife’s best friend’s husband asking if she was there. I told him no, she was visiting family in FL. The guys voice cracked when he said that’s not what she told me. I guess he didn’t know and I’m a young teen at the time not taking social ques and just yapping away like oh yea they will be gone for like two weeks blah blah visiting family blah blah planned it all out blah blah and he’s was real quiet then said thank you and hung up. He later killed himself jumping in front of a train.

I found out my Uncle died in the woods having sex with my Aunt, not hunting.

My dad put him self through University debt free, betting on horse races. Found out when he introduced me to a old school, chum.

That the reason why our group chat sometimes went silent after I asked a question was because they had another group chat without me where they discussed how annoying I was. I found out when one of them posted in the wrong chat. At least now I know I'm sometimes very annoying, and that I don't want to be friends with people who don't like me that much.

I discovered my supposedly single coworker was actually married when her husband called the office looking for her during a "girls night out." She had told him she was working late but was actually at a bar with some guy from accounting. The awkwardness when I answered that phone call was unreal.

I was at an event with my friends in foreign country and they were some other people sharing some photos of their late family members. My father passed away when I was 1 and I saw a picture of him on this girls phone. Looks like my father had a ex wife and 3 daughters I never knew about.

My great-grandfather was born in 1845. My great grandmother was born in 1859. I found the family grave only to find that their first-born son (my great uncle) was born in 1871 when my grandmother was 12 year old.

I found out my mom gave my cat to the humane society. She was caring for my cat while I was in college, a job she volunteered to do. The cat I bought everything for and adopted with my own money. Turns out she had lied and said he was at home being silly and happy whenever she came up to visit. She forgot to hide the humane society paperwork in her car and she asked me to get something out of her car. By the time I found out, it was too late to get him back from the humane society. Luckily the compulsive liar is out of my life for good. I hope my cat is having a good life with his new family and they give him all the love I gave him.

One of my female friends had been hanging out with another girl a lot and quickly becoming best friends. I completely randomly had a class with another girl who just happened to know that girl (I think they used to be roommates or something) who told me she (the girl my friend was getting close with) was legally married to a guy in New Zealand who was not the same guy that she was dating here in the US. (In her defense it was mostly a legal technicality, she wasn’t like actively cheating on her boyfriend here. That being said I don’t remember if the boyfriend was aware of it or not.) Anyway my friend one day was being really coy and smug and doing the whole “I know a secret but I can’t tell you” thing so I just immediately blurted “She’s married in New Zealand?” and she was like “how the f*** do YOU know that?” lol

My dad had an accident when I was a baby and was paralysed. I was always told he fell off the ledge of a bridge whilst showing off drunk to his friends (he was 24 and a roofie with notoriously great balance). I always believed this story and would repeat it to anyone new in my life who asked why he was in a wheelchair. When I was 16, an alcoholic auntie was drunkenly moaning about how he never tried to do anything with his life ‘after your mum left him and he jumped off that bridge to kill himself’… My stomach dropped and I felt really betrayed that nobody had ever told me the truth. I also felt exponentially stupid for not realising. He still doesn’t know that I know.

A few years back, I convinced myself my mom probably had a child she gave up for adoption. She’s always been super secretive, so it just felt like it fit. I never actually asked her as I didn't think she'd tell me the truth anyway. Then one day my husband went to visit my parents. When he got home, I could tell something was on his mind, but he wouldn’t say what. He asked what I knew about my mom's life before meeting my dad. I told him I didn't really know much but that I was sure I probably had another sibling out there. He confirmed it.

That me and my older sister have different mothers

That my dad had a wife before he married my mom. My sister and I used to love looking at our parents wedding album when we were kids and they kept the marriage license in between some of the pages. We looked at the license one day and, weirdly, my dad is listed as divorced while mom was listed as single never married. When we asked my mom about it, she yelled at us for touching her stuff and to stay out of her room without permission. They never talked to us about it. About 20 years or so later, my dad decided to randomly confess his life story to a home health nurse visiting the house: not only was my dad married before but he was married when he and my mom got together (she was 16, he was 23! And her boss!!!). And the reason he left his wife for my mom was because his wife couldn’t give him children and “a man needs to be a father of his own”. I was sitting there in the living room next to my husband, watching horrified at what I was witnessing. I was in the midst of having issues conceiving children myself and hearing my father, the man I thought was the greatest example of a husband, casually talk about my worst nightmare come to life, was too much. I left the room and my husband followed and held me while I cried for hours. My parents, of course, thought I was overreacting, because “obviously they were meant to be together and it had nothing to do with me.” That day broke something in me. The world got a lot uglier and my trust in everything pretty much shattered. Thank God for my husband. Took us 12 long years but we did finally manage to have our little son.

Discovered someone I trusted didn’t actually like me

Not a secret, but my best friend of almost 20 years turned out to be my cousin.

That my brother was actually my half brother and was born with a completely different name. When I was 16, I found a birth certificate on the kitchen table with a name I had never heard, but my mom was listed as the mother. Turned out she had been married before I was born to a different guy, and had a baby with the guy and then divorced. I was stunned!

Someone posted a very similar story here as well. My childhood friend growing up is actually my cousin. My friend/cousin's mother slept with my uncle, but they broke up while she was pregnant. He refused to say the child was his, because she slept around, but it's painfully obvious he was the father. She married someone a few years later. The husband adopted him and they never told him that it wasn't his real father. I get the whole "mind blown" thing because once I found out, it's like my entire childhood flashed before my eyes of all the moments when people would ask if we were siblings or cousins, because we looked and behaved so similarly. Almost every stranger would ask that. I guess he found out in his mid 20's, a good decade after I knew. However by the time I found out our mothers had grown apart, so we did also, not hanging out or ever seeing each other anymore. I've run into him maybe twice over the past couple decades, but just very brief conversations in passing, and never brought it up.

Found out two people I knew were secretly dating for months… just by seeing a random message pop up on one of their phones. They acted like total strangers in public, so it felt like I’d unlocked some hidden storyline 😅

I was subbing on a Special Ed bus and got a super sweet fifth grader first thing in the morning. Because the second rider was sick, we didn't take the long way out to his house to pick him up, so I had to sit with the kid for twenty minutes at the school before I could let him out. He told me he knew a kid at his school a couple years ago who could have been his twin. They even swapped places for a couple classes every now and then, and the teachers never knew. One day, he told his mom about the other boy and asked how he could look so much like him. She admitted to him that he was adopted when he was three days old, and that the other boy he knew and was best friends with the past two or three years was his brother... He went to school and told the other kid what he learned. The other kid told him, "I thought you might have been my brother but was afraid to say something. My mom had so many kids she was forced to put a couple of them up for adoption." I probably shouldn't have, but I asked how many children she had? He said twenty seven! I held it together and did not make a surprised face. I thought that was insane and just not possible, but the bus monitor piped up and said his mother had also had something like twenty four kids and gave several of them away when they were babies, and he was raised by his grandparents. What the hell!?

i visited my cousins in america when I was about 12 y/o (2006ish). we had the same taste in scene/emo music so I asked him if he would just put everything he had onto my iPod, so you'd connect and just click 'sync iPod' and everything in your library would go onto the device. I had just been gifted a newly released iPod that had a color screen and video capabilities. So he did that and all was well. when I was flying back home i saw a video on the iPod and opened it, it started with a man talking with his student. turns out my cousin was gay and he accidentally synced his 'video collection' onto my iPod. I told my brother but we've happily kept his secret for over 20 years now.

That I’m not the oldest child. My mom had a kid with someone not my dad and for unclear reasons she decided to have the kid in Michigan (she was living in Virginia at the time). My aunt ended up moving to Michigan and worked in a hospital where my older sibling went for treatment. My aunt saw her birth certificate and asked her if she wanted to contact her birth mom. So, one day there was a knock at the door and before I answered it my mom told me that it was my sister knocking. I had no idea until ten seconds before I met her.

My boss was embezzling/misusing company funds. He made me manage his work calendar (though it wasn't anywhere near my job description) and he was taking an upcoming vacation he wanted me to clear meetings during. He mentioned he was taking his family to Puerto Rico. A few weeks later, my colleague who managed our company frequent flier rewards account noticed someone had drained a ton of points flying 4 people to PR. I caught just the tail end of him saying this and thought he was talking about someone's personal trip, so I said "oh yeah, [boss] just took his family there!" One thing lead to another and not only did boss get fired, but lost his visa sponsorship and ended up moving back to his home country after they found several more concerning transactions he had made with company funds. Yikes.

That my ex was an e*****. Found out from her friend because the friend realized I was apparently way nicer than my ex told them I was and the friend felt bad and told me.

Santa doesn't exist. I was 6yo, was ill as f***, woke up to vomit once again. Found the weird assembly of my parents and aunts/uncles wrapping toys.

My colleague seemed like a productivity genius—he closed tasks three times faster than anyone else. I once walked into his office after he was gone and saw an open chat room where he was paying freelancers from another country pennies to do his work. The whole office thought he was a "rock star," but he was just a go-between.

Picked up the wrong phone and saw they were texting two people the exact same “I miss you” message

A woman called our workplace asking for a co-worker of mine. I explained he was out on vacation and she thanked me and hung up. He came to work the next day with a black eye and had a story about bumping into a cabinet door. I honestly didn't catch it right away, but another co-worker (f) he was friendly with, was also off that day. He didn't talk about his girlfriend after that.

Not me, but my sister. She signed up for [Ancestry.com](http://Ancestry.com) and did the DNA sample. When she got her results, they told her that someone had been flagged as either a half-sibling or a cousin. For a while, we were wondering if our dad had had a kid when he was younger because this woman was older than both of us. My sister contacted the woman, and long story short, she's our cousin because our uncle got a girl pregnant in high school, the girl never told him about it, and our cousin grew up thinking some other guy was her dad. What's sad is that when my dad told our uncle about it, he denied it even being possible, and then he ended up dying suddenly from an unknown heart problem about a year later, so he never met his daughter or her kids.

Aged about 6 I was looking for some paper to draw on, went through one the drawers in the kitchen and found a letter my mom wrote to the woman my dad had an affair with.

That my cousins ex did gay p***, he’s fully straight - just poor.

One day when I was about 10 years old we were doing some family paperwork at an office with my mum, and I happened to see on a specific document a name I didn’t recognize under my grandmas spot. In the elevator I asked my mom about it and she told me that my grandma wasn’t my grandma, that her mother died when my mun was 2yo from leukemia but it wasn’t talked about it. Actually my grandfather hided every photo every memory of his first wife (my mum’s mum) out of grief and the first time my mother saw a picture of her mother was when she was 40 years old. He was a b****** in a lot of ways

My absolute best friend, told my then current girlfriend that she loved me, and always did. I was floored.

I found out my late grandfather passed away intestate leaving behind a small fortune (money, property, land, etc) and me as his only living relative. When I became aware I did some digging. I wouldn’t have been hard to find so I should’ve been contacted and inherited it all. Turns out a much younger woman who is supposedly his wife inherited everything. The only catch being there is no record of this marriage. I hired a lawyer to confirm my suspicions and she also couldn’t find any evidence of marriage or civil partnership that would entitle her to his fortune. She said I had a very good case if I wanted to pursue it, but wouldn’t be able to do it pro bono. I couldn’t afford to pay the fees myself so I’ve bookmarked it to look into one day when I have the money.

Found my nan's death certificate, she died of alcoholism, never had a clue

I found my half sister on Ancestry. We don't speak to our mother anymore.

Found out my mom had cancer when I was a toddler and never told me when I was describing her other health problems to my grandma, and my grandma was like and she also had cancer. My grandma felt so bad about it though.

I found out my dad had been married to someone before my mom. They married right out there of college so the thought never crossed my mind. I was sorting through some things in my grandparent's house after their seath and ran across a picture of her. My mom said, "Oh, that's your father's first wife." The "whut?" must have been obvious as I sat there thinking I must have misheard.  Apparently he got married at eighteen, but it didn't last. He never breathed a word. I just put the picture back and said, "I guess it isn't really any of my business." My mom very much disagreed, but I never saw any reason to discuss it further.

Looking at our family tree I noted my Dad was born 6 months after his parents were married. Now, understand my Dad (a wonderful man in all respects) is a very devout Christian, and so I found the idea pretty amusing that he was conceived out of wedlock. When I asked him he just laughed and said "yep, those things did happen back then!". My Grandad had just returned from WW2, he saw a pretty young lady, and well I'm sure things happened really quickly and their wedding plans were brought forward shall we say.

My girlfriend was kissing me differently. I thought I was joking when I asked "wow, who did you learn that from." She told me who she learned it from. And when. And where.

I found out i have a sister that my mother nor my father knew about.

That I had been a secret child, born from an affair. Asked my grandma why all of my cousins had an up to date picture on the wall whilst mine was me at 2,5 years old. Told me it was special because it was from meeting me for the first time after just learning I existed.

I accidentally found out my landlord had been charging me for “utilities” that were never even connected to my unit. I only caught it because I noticed the meter numbers didn’t match the bill, so always check the basics when something feels off.

I was 18 when I found this out about my mom Found out by accident my mom used to be married to a British guy in the late 80s but divorced him soon after due to him being abusive. This came about when I discovered a photo album of my mom's and saw a wedding photo of her and some dude who was not my dad. My mom looked at me like I discovered something horrible. I was just curious and asked her who this was. She explained the backstory and it broke my heart. She said the only reason she kept the photo was because she looked pretty. She didn't want anyone to know about it (especially my dad). So, I was sworn to secrecy forever. My dad passed away never knowing that my mom was married before him.

Who my real father was

Doing some genealogy I discovered my '16 1/2 years younger than any of her sisters' Aunt, is almost certainly my cousin. I guess it's quite obvious in retrospect!

We found out my aunt had stolen almost all of my grandma's money because the card declined when my dad tried to buy her toothpaste. Between 3 accounts there should have been about $370k, the account that declined (at $970 overdrawn) should have had $230k alone. Through a twist of luck, my grandma was with us when she broke her pelvis and needed to be in assisted living in our city for a few weeks. It was end of the month and things were tight for dad so he used his copy of her card for a few essentials she needed. Had we not discovered it then, she wouldn't have had anything left. Right now she has about $25k. She doesn't want people knowing so my aunt's life isnt ruined or I'd have already made a tiktok with a gofundme for her. But the important part is she stayed with us and is healthier than she's been in years and is treated like a princess instead of the burden my aunt made her feel like. We had no idea it was so bad for her there or we would have stepped in much earlier.

Not really that serious but when I was finishing 8th grade and about to go to high school I failed my math final something fierce. I overheard my parents discussing how they were going to tell me that I would have to retake the exam and start high school in remedial math. At least I saved them the trouble!

My wife was in an intimate relationship with her best friend and also had an affair with my best friend. Still paying thousands out to that woman for the pleasure of having my life flipped upside down 

I was at a Mensa meetup. One of the other members was the school secretary at my public school. She wondered why I hadn't gone to the gifted student program I'd qualifies for. The what? I asked my mom why they hadn't put me in the program. She said they didn't want to take me away from my friends at school. #Of which I had NONE. But maybe I *might've* if I'd been in the program and met some students who didn't think I was the weird kid who skipped two grades and was therefore much younger than everyone else. What mom didn't say is why no one told me about it at the time. >!Sure it was 50 years ago but I'm sure I'll get over it any day now. !<

My manager accidentally cc'd me on an email what a new coworker was going to make. They had less experience than me, but was going to be making more plus getting a sign on bonus. That was a "fun" and awkward conversation.

Found out my quiet, introverted neighbor was a semi-famous jazz musician in the 80s. I was helping him carry groceries and noticed a vinyl of an album on his shelf with his face on it. He just smiled and said "that was a different life." Never mentioned it once in 3 years of being neighbors.

When i was learning bicycle and that day i found out how does the front brake works by complete accident.

While looking through my dad's bedside drawer as a kid I found a letter my mother wrote to him, telling him she wanted a divorce. It never happened but I realized then their marriage was in serious trouble and I was worried what would happen to me.

That my dad was once married to a 16 year old. He always talks about his ex wife but never anything specific. Just things like she’d leave piles of dog poop on the ground and cover it with a Kleenex until he got home. I ended up on some marriage record website but I didn’t know if it was legit so I looked up his name. They apparently divorced within a couple of months of her turning 18.

A friend asked for my help moving furniture in their bedroom a few years ago. They forgot to move/hide some k**** stuff they had under the bed... I mean, no judgement at all from my end... whatever floats your boat. I just really did not need or want to know about their bedroom activities.

I found out my husband was cheating on me when he got a text from his affair partner while we were sitting in the grocery store parking lot. Just a 😘. And I happened to be glancing at his phone at our grocery list when it came in.

Long time ago but we found out That my dad was definitely cheating on my mom bc we stumbled across v***** hidden in the seat of his car

My parents were in the process of divorcing (or, more accurately, my mom was attempting to escape abuse) when I was conceived. I found the paperwork when I was 9 and it really messed with my head for a while. If there’s an upside to the story, it’s that, despite everything she endured, she was an extraordinarily kind and loving mother. I recognize so much of her sweet nature in my son that it sometimes feels as if she’s still with us.

My family isn't actually from the Czech Republic. They're Hungarian. My mom just told everyone that because they hated being Hungarian. So much for all those Czech heritage tattoos I got.

My younger sister and I are twins. My parents were having dinner at our house with friends while all the kids were upstairs playing video games. The parents were a few drinks deep and talking loudly. I heard my mother telling the group how they used artificial insemination and in vitro to conceive. I learned that my sister and I were conceived in the same “batch” and that I was born from the first implantation and my sister from the second. Both of us, I’ve since learned, had other embryos with us that didn’t take.

I found out one day while reading a listnook post that its a common trope of when the parents have the dog put down they tell their kids that they gave her to a farmer to run all around on a big field and that she'd be so happy to just run and run. Welp...Nanny?
