They know he just doesn’t get consequences. He only gets told not to do it. This year he tried to grab my arm and partially bit me so I tried getting him off. They made me apologize later because he had tried so hard to hurt me that he busted his lip and I had accidentally scratched him while getting him off of me.Do your parents know?
More specifically, are they aware that that behavior is absolutely unacceptable, regardless of who is doing it to who?
