My Little Lady

JP's teacher called me to tell me about something that had happened at school on Friday.While at art a boy was messing with JP and she had told him many times to stop. The teacher was about to come over and talk to the boy about not listening and being rude and that's when she heard JP say, "If you don't knock it off, I am going to kick your ass!" LOL!!! The teacher said the boy had it coming, but JP just can't be using that kind of language at school. I thanked the teacher for keeping me informed and talked with Julianne about it. I am just confused as to whether or not I should be embarrassed or proud.
