Anger sucks. I get angry, and it's no fun. People I know get angry, and it's no fun.
The thing about anger is you never feel good afterward. You feel empty, maybe guilty and almost always sad. That's probably because anger is a secondary emotion – there's always a reason why we're angry! But I guess it's easier and maybe feels better (at the time) to be angry rather than confront the source of hurt that's causing the anger.
Anger is especially awful when it leads to fights. And while I've seen many books on how to deal with anger, or how to rid your life of anger, or how destructive it is, I think if we had dance fights (like the guys below) instead of real ones, we'd feel a whole lot better.
