There are times that happens to me as well. Usually, it's the result of bottling things up when something annoys/angers me instead of taking care of the situation when it arises. By the time the "festering ball of rage" manifests itself, I've fairly forgotten the things that were bottled up in the first place. It takes me the better part of a day to calm down as well. I do my best not to take it out on innocent bystanders, but sometimes there is collateral damage that I have to apologize for afterwards. Like you, I don't enjoy it either, but at least I've attempted to "remove the cause ... but not ... the symptoms".

On a lighter note, the little $3 theater here in town is showing a sneak preview of "Iron Man" at 8PM tonight. Guess who's going to the movies tonight?
