Larry I know what you mean - my wife is very good, but a few times a year we get that kind of thing, and it usually has nothign to do with what she is upset about, just a sudden explosion.
my wife has a friend viisting, who is a 40 something single woman, who works in a non-profit. she is a nice enough woman, but horribly indecisive. she has been with us for two nights, for the jewish holiday, and she is driving me nuts, basically because she is indicisive.
honestly, my boss is a woman, and she is the best boss I've ever met, but most women have such huge roadblocks to management - between the whole hormone thing and the indicisiveness, I don't know how they get through life without help
