Never rave, tear your hair, or swear there has been cheating all around, even if you have lost ten cents on the game. Either bear your losses with equanimity, or never gamble.
Never treat aged and venerable persons like budding hoodlums, or make riotous fun of their wrinkles or their bald heads. You may be old yourself, some time, if not assassinated for your bad manners.
Never neglect to give precedence to ladies, both on entering and quitting a room. A brutal disregard of this injunction might cause you to be led out by the ear.
Never, as hostess, insist that a casual caller shall send for his trunk and stay a week or two.
Never, as host, ask him hilariously if he is well over his last drunk, and getting primed for another. This is not in good taste.
Never hurry your departure, as if your legs were sticks and your body a sky-rocket.
Never, on the other hand, tarry from, say, four in the afternoon till three in the morning. A light, flying visit is one thing, taking root another.
