loopy, my boy who was 7 at the time was beeing bullied in school along with a number of other children, this bully actually punched and head butted the children, and no matter how much you complained to the school {and their were a few complaints} nothing happened to this bully apart from the odd day or two suspension{basically no other school would take him.
My wife kept it quite from me, but my 7 year old came home one day from school with a bump on his head, i went berserk, and when the bully came out the school the next day i told him i would slap him if he touched my boy again, well his mum and dad was standing behind me, and the mother {who was a right mouthy bitch} said, you have a problem with my son you have a problem with us, i said no problem, apologised for having ago at her son, and promtly threw her husband up against the wall, and said if you value your life, disapear with that fat s**g of a wife of yours before i break your f*****g neck.
lets just say i was everyones favourite parent at my boys school afterwards, boy did i feel good about it
