The woman who has a keen sense of humour is a terrible one to make love to. The romantic one will find charms in all your shortcomings, but the other is inexorable. She is constantly on the look-out for something to laugh at; nothing will escape her. And you know that, if you laugh, love-making is out of the question.
I know a woman who was radically cured of her ardent love for a man because he had, near the tip of his nose, a tiny little wart which turned alternately white and red while he got passionately engaged telling her the sincerity and intensity of his love.
If you are bald, never make love to a woman taller than you. Looked at from below, you are all right.
Never let your lady-love see you without a collar, no, not even the very wife of your bosom. A man's head without a collar is like a bouquet without a holder.
Never let her see you asleep. Maybe you sleep with your mouth open. If you are married, let your wife sleep first. When you are quite sure she is off, let yourself go—and be careful to wake up first in the morning.
Never tell your lady-love that you are very steady in your affections, and that every time that you love a woman it is for ever. If you think she will enjoy the joke, you overrate her sense of humour.
If your wife or sweetheart be in love with you to such a degree that she tells you she could never survive you if you happened to die, reassure her and tell her that there is a way out of the difficulty—her setting out first.
Don't let your wife see you shave. Your idiotic, cowed look, your gaping mouth and grimaces are as many infallible remedies for love.
Never indulge in any little objectionable trick before the woman you love. Great affections should never be trifled with. Madame Bovary, in Gustave Flaubert's famous novel, took a dislike to her husband and went helplessly wrong, because the latter, after eating, used to clean his teeth by promenading his tongue inside his mouth. I sympathize with the poor woman and feel rather inclined to forgive her.
