“A man doesn't want to feel that a woman cares more for him than he cares for her. He doesn't want to feel owned, body and soul. It's that damned possessive attitude.

Some have glanced off, doing hardly any damage. It is as though somebody had shut his eyes and then in a frenzy struck blindly again and again.""C'est une femme," said the chef de train again.
