My 11 year old son is getting bullied at the bus stop by a 13 yr old. This kid has always been a problem in the neighborhood but his parents do nothing to discipline him. I don't think they really believe their son is doing anything wrong. He does things to humiliate my son, like come up behind him and steal his backpack or verbally harrass him in front of the other kids. My son doesn't want to make things worse, so he tries to ignore it, but I know it is getting to him. He says he doesn't want us (his parents) to get involved, but I don't think he can resolve this on his own. Any suggestions?
