If a man prepares dinner for you and the salad contains three or more types of lettuce, he is serious. No man is charming all of the time. Even Cary Grant is on record saying he wished he could be Cary Grant. When four or more men get together, they talk about sports. When four or more women get together, they talk about men.
Men are less sentimental than women.
No man has ever seen the movie THE WAY WE WERE twice, voluntarily. He just didn't want to call you. Men hate to lose. I once beat my husband at tennis. Getting rid of a man without hurting his masculinity is a problem.
