If ever a man and his wife, or a man and his mistress, who pass nights as well as days together, absolutely lay aside all good breeding, their intimacy will soon degenerate into a coarse familiarity, infallibly productive of contempt or disgust.

If one could be friendly with women, what a pleasure -- the relationship so secret and private compared with relations with men. Why not write about it truthfully?

What people don't realize is that intimacy has its conventions as well as ordinary social intercourse. There are three cardinal rules -- don't take somebody else's boyfriend unless you've been specifically invited to do so, don't take a drink without being asked, and keep a scrupulous accounting in financial matters.
