Women especially love a bargain. The question of 'need' is irrelevant, so don't bother pointing it out. Anything on sale is fair game.
Women never have anything to wear.
Women need to cry. And they won't do it alone unless they know you can hear them. Women will always ask questions that have no right answer, in an effort to trap you into feeling guilty. Women love to talk. Silence intimidates them and they feel a need to fill it, even if they have nothing to say.
