I try to model for him how to ask people to move nicely, and how to direct pets without the aggression, but he does not get it. To him, he wants people to leave him alone and when he acts like that, they leave him alone. Problem solved. I've tried asking him how he would feel if people treated him like he treats others, but he doesn't seem to relate to that either.
Has anyone else dealt with this issue, and how did your teach your child to be a polite, functional individual?
