Just today I spoke with 3 families with angry and agggressive teenagers. They came to see me because they were concerned that their teens couldn't manage their feelings and actions appropriately. In all 3 cases the teens were being mean to their siblings. The parents were concerned that their kids were just too irritable and didn't know how to relax. I spent a lot of time getting to know about the dynamics of these 3 families. In each case, there was at least one parent who had an anger problem that preceded the teen's anger problem. No tremendous surprise here. Teens learn how to respond to situations by watching their parents behavior and emotional reactions. Parents-be aware of what you are modeling. Good luck.
