I was long annoyed by my mother who made me all sorts of annoying housework because "it's a little boy's job". Lawn mowing even though I'm allergic, all the dog's poop on the excuse that my sister vomits too easily when picking it up, snow shoveling even though I've always been by far the weakest, physically, of the family... THAT has aggravated me so much forever. And without a word, since I transitioned, she doesn't even think of suggesting that I do that kind of boy's job. I wish I could tell her the definition of sexism.
Also, there's clothes. Mostly, casual clothes was all stuff that a girl could easily wear too, so I wasn't intensely bored by what I wore on a daily basis. But when came my graduation ball after high school... You're SUPPOSED to wear a tuxedo. Ew. I really didn't want to. So I made my mother search left and right (vengeance!) for something a bit more colourful and acceptably pleasant to wear. I looked pretty unique in a light green shirt. And I'm pretty sure I was the only "guy" who went to the hairdresser to get my hair fixed before the ball. My friends had told me it made me look younger (aka girlier but don't wanna say it like that). One of the only times in my life I had relatively short hair and thought I looked cute in it. I'm really glad I didn't let myself be taken away by gender expectations too much for that once, and managed to still make that night a relatively good memory.
And... Ew, separate groups for boys and girls. You just reminded me of that. Almost all boys would have to play dodgeball, because girls would reject them from their own games (skipping rope and some other stuff that I forgot), and I think boys only reluctantly accepted a girl to play dodgeball. Well, it depended on the school. I'm pretty sure that between the 3-4 primary schools I went to, there's a few where everyone without exception had to play the same game (mostly dodgeball; occasionally capture the flag). That does have its disadvantages depending on the point of view, but the good part is that I didn't feel all that isolated in a world of boys...
And then there was that summer day camp where I went for quite a few years... Groups after 4 years old were entirely separated by gender, and they barely ever met, even eating at different times. They should have known how unhealthy it is for children to be separated like that, sheesh. I wonder if it's still like that today.
Oh yeah, and one summer my mother had more money, she put me into a full-on summer camp, for two weeks (I think). A camp exclusively for boys, with the only women being the lifeguards and a secretary. They had fun activities, but... Come on, a camp exclusively for boys. Even at my young, naive age, I asked whyever there weren't any girls and found it stupid. That implied some "awesome" stuff, like "Indian Day", where the whole day is themed around Natives, and everyone is forced to go shirtless. How I cried and refused before they could finally get me to do it on the condition that I had a towel that I could keep on me at all times.
