The women usually end up following men. When a woman says she'll be ready to go out in five more minutes, she's using the same meaning of time as when a man says the football game's just got five minutes left. Neither of them is counting time outs, commercials, or replays. And so on. Women on a girls' night out talk the whole time.
Men use restrooms for purely biological reasons.
Women use restrooms as social lounges. Men in a restroom will never speak a word to each other. Women who've never met will leave a restroom giggling together like old friends. I know that stays steady, the only institution I know that works, is the family. As the family goes, so goes the nation and so goes the whole world in which we live.
