Are you also 5'5 and a 130 soaking wet? You sound like a gigantic vagina
I could very well be, but at least I woouldn't allow myself to get bullied.
Look, there are bullies. There will continue to be bullies no matter who you sue or who you bitch to. Sue the kids parents and everyone at school finds out about it. Go on the news, everyone at school finds out about it. You think the kids are going to stop bullying because their parents tell them to. It is more of a groupthink situation in high school. Kids just go with whatever their friends are doing. Send him to another school, same problems are gonna occur. Any way you take it, he is going to keep getting bullied. Hell, bullies don't stop existing just because you get older.
You can't just teach the kid that mommy and daddy will always be there to sue someone who is being mean to the him. He will sooner or later have to stand up for himself to stop it. Teach him that and he will become a better person.
frick man, how hard is that to understand?
