Don't think you're alone handling this issue with girls.... it's happening with boys too. What I told my son is that it is HIS choice to play with him... if he starts acting ugly toward him to be direct and say "that's not how a good friend acts" and to turn and leave immediately...walk away and do NOT look back... I remember going through this as a kid too... I really do think it's just a way for children to learn conflict resolution... don't turn the children's issue into your own... as you will NEVER find someone with a parenting style like yours... I, too, feel like the parents of this other boy that was just being a poop to my kid didn't handle him appropriately either... but it just wasn't worth the fight to me... my son, actually on his own, has completely stopped playing with the boy at all...and unfortunately, the friendship with the parents has waivered a little... but we just choose to put people in our lives that compliment everyone... it's hard but you gotta do what you gotta do -- that is best for YOUR family
