Good point, Bluebell, about anger being the first step in getting in touch with what needs to be healed. Some people get stuck at this level and are never able to progress. We see them everywhere. The people who are ranting in the bus station. (Usually has to do with something that happened to them years ago. Somebody comes by and does something irritating and that old trigger is pulled once again. Hooked in by hatred.)
Or the person who DOES kick his dog because his wife did something that made him angry.
That initial stage of recognition that one is angry is very much like kindergarden, I think, Mlittrell. It comes from our most primitive impulses - fight or flight. A human at his most crude stage of development.
Fortunately we are not animals and so people, who have knowledge about change and harmony and social concerns, learn that there are other options. They're ones that keep us from walking into situations where we will act like an animal and, in turn, be treated like one. Locked up in prison, for instance.
Although it's a matter of courtesy, social order and intelligent connection that's not what it is about. I see it as a matter of commmon sense and self-preservation to learn to act in public in ways that work to our ultimate growth and benefit.
