What is a stupid argument you and your sibling still have even though you are both adults now?

Who Mom loves more, somehow still an active debate years later 😅

Who put the d*** on the snowman?

A Mario Party 2 victory I won by a single coin after stealing them from my bro with the last move. Also his continued insistence that he didn't delete my nearly completed Banjo Kazooie save on purpose!

who's the adopted one

Who mom loves more 😭 We both know it’s childish, but somehow it still turns into a full debate every time.

Who’s the better driver, every time we argue, I just wonder how we both survived childhood.

Who was the favorite child growing up, still somehow turns into a full debate every time we meet.

me and my brother still argue about who gets the last piece of pizza from our childhood. like we’re in our 30s and it’s still a thing 😂

Who travel in, as the front passenger when we're going somewhere and take only one car on a Day out with our family.. haha

Who's supposed to make bed every morning

We both are married now but still fight for the tv remote

Whether or not they can call me "kid" or give me life lesson advice. I'm in my 30s. They are 9 years older than me. Both married with kids making similar salaries. My kids and their kids have less than a year of an age gap between them. Like, bro, I'm good. I don't need your advice. You are not older and wiser. We are at the same stage of life.

Who was the “favourite child.” We’re both adults, fully aware it doesn’t matter, and still somehow bring it up like it’s an unresolved court case.

What food to eat lol

Me and my brother have been moving one of those shitty Apple stickers you used to get with a new iPhone for the last twelve years. I’ll stick it on his bedroom door and then a few days later it will end up on mine. Each time in a slightly more concealed place. Sometimes I can go months before I notice it and immediately stick it back in his room somewhere. We are now both adults and moved out but whenever we go back to mum’s house it starts all over again.

Some of us put washing up liquid in my granny’s ice cube tray, i think it was one of brothers and he insists it was me. Anyway this was close to 40 yrs ago

Whether pineapple belongs on pizza

Who's better at Super Smash Bros Melee, which we've been playing regularly for more than 20 years. For a long time I mained Doc and he mained Peach; that matchup was for many years much more even than it should have been given how much better Peach is than Doc. But eventually he solved that matchup and I had to switch mains to keep up. The current state of our metagame: his Peach beats my everything-except-Ness (and sometimes Falco). My Ness beats his everything-except-Sheik (and sometimes Roy). His Sheik goes even with my Falco, but usually loses to my Marth. My Marth loses to his Ganon and Peach. So neither of us has a character that reliably wins against the other, and if we're seriously counterpicking characters we end up going around in circles. Stage pick also seems to influence it; he has a positive winrate against me on every stage except pokemon stadium; on stadium, I have something like an 85% win rate against him.

My sibling and I still argue about whether cereal should be poured before or after milk, we’ve been going at it since we were kids.

Who’s the favourite. It’s obviously my sister

I’m the master 😂
