There is one boy in particular who is about 2 years older than DS and they have been friends for about 5 years now. In the last year, this boy has really gotten out of hand. He is rude and disrespectful to his parents and to other children. I had to suspend him from the karate school for two weeks for his attitude and since then he has been the perfect angel there. We had him on a "Three strikes" rule and still do.
He fancies himself a "player" and I've overheard him several times talk explicitly to other kids about what he wants to do with girls. All talk, maybe, I don't know, but really it's enough to make me blush sometimes. Between his talk, his mouthiness, his outright disrespect of other people, I Just don't like the kid and I'd rather my son not hang around him without me being there.
I've refused to let him stay over our house, and I've told my son he can't stay there. Am I right about this? Usually I'm ok with DS making his own decisions about such things, but this kid is really not the kind of person I want my son to get ideas from. For whatever reason this kid is very charismatic and other kids just gravitate toward him, my own included. I've talked to DS about what it is that makes him like the boy, and he doesn't really have an answer. They've always been good friends.
Oh and I have talked to his mom and stepdad on several occasions. They are frustrated with him but don't know what to do. They bribe him a lot to be good, but once he gets what he wants, he starts all over again with his behavior.
