I dont think engaging in retaliatory violent behaviour is the answer. I think it teaches kids to "get even". I try to teach my children that they are *above* that & I also point out that the negative behaviour of children is often due to poor parenting. I encourage my children to vocalize when others treat them badly. If the situation is not remedied they are expected to *leave* the situation. They are not to allow the other person to continue to treat them badly. If the child in question follows them, come to ME, mama will handle it!
