I was six and it was in my neighborhood. Then it lead to school when I was eight. I wasn't picked on often at school when I was six and seven and I think it was because I was in special ed full time. Then when I was moved to my new school, that's when it started.
Before age six, I don't ever recall being picked on. Just occasional meanness and that's it.
