This is your son not letting another kid bully him. Good for him. I know I may get reamed for that, but that's my opinion. We always tell kids to not fight, but sometimes I think it's necessary. I mean, really, do you want your child to be at practice and constantly be picked on? Your son probably DID tell that boy to leave him alone and probably DID tell an adult. Sometimes that makes them seem like a "tattle tale" (at least to the other kids). Now that your son threw a punch he probably wont be picked on anymore.
I have ALWAYS told my children that I don't want them to fight. To use their words. To tell an adult. And then, if the kid doesn't get it, they are allowed to defend themselves and I will back them up.
