Not easily. If I am under a lot of stress, I get irritated easily, but not angry. If I do get to the point of angry, I am angry for a long, long time, like a slow burn...and I never forget. Fortunately, that requires very specific circumstances, like someone messing with my kids, which is pretty rare.
My redheaded rage only kicks in every now and then. It takes quite a bit for me to get mad for the most part. But mess with someone I care about and you should be ready to deal with my irrational anger >.>
What does, is impoliteness and inconsideration.
