I repeat over and over to myself that I am the adult, and that adults should not behave badly because it does nothing but teach the kids to act the same way. Kids are so skillful at pushing adults' buttons! I just keep reminding myself over and over that I am the adult, and I will not allow them to manipulate me into destructive behavior. Kids are still learning. They have not been on this earth very long and need our patience, understanding and guidance. They not are trying to make us angy on purpose (well, usually they're not, lol).
