How do you convince your parents to let you shave your legs?

I am 12 years old, in 7th grade. My entire grade (and school!) shaves/nairs/etc their legs. My mother won't let me, she says I do not have hair. But I see it and get very humiliated. On multiple occasions, my friends will accidently rub against my leg and be say, "wow this is awkward . when was the last time you shaved?" My parents still don't say there is any hair on my legs.

for real, you dont need that, you don't need to call the atention of any boy on that area, but, if you want to convince your parents, try to bring a friend as a support, also try to talk just with one parent alone, like your mom, and tell her thay is not because you want to have a boyfriend(they are sometimes worried about this), is because you feel bad and all your friends are bullying you

Show them the hair and tell them how embarrassing it is for you when your friends tell you its awkward. Also using a cream like nair would be better than shaving. Shaving would just lead to fast regrowth and maybe even thicker hair.

If you shave your öegs or not is YOUR decision. If you want to, do it.
