Illogical anger is pretty much always simmering on the back burner for me. Like a pot of forgotten stew. Not necessarily the worst thing in the world. Until it boils over and stinks up the joint.
Sometimes there is some logic behind it, but mostly it's set off by things that are beyond my control. Stupid people, stupid rules, stupid situations. I guess you could say that stupidity is one of my hot-button issues.
So here's my advice, world. Stop being stupid. It will save me so much rage.
