I was a Russian dancer in my elementary school production of Fiddler on the Roof when I was in third grade or fourth grade. I was one of the younger kids accepted into the play, and the plays were pretty impressive, let me say.
Don't peak in high school.
I think being mean to people in high school is healthy. It's sort of like you're in this situation with all these other kids and sometimes you need to get your aggression out. And if you'd had people be mean to you before, it really does build character.
