In criticising a play or a novel be careful to avoid long and discriminating criticisms. You should either “knock” or “boost.” Try to remember that there are only two kinds of plays or novels—they are either “bully” or “rotten.”

If a few people in the smart set are entertaining a stranger at lunch, it is de rigueur for them to converse with each other entirely in whispers and always on subjects with which he is absolutely unfamiliar.

In discussing literature at a lunch or dinner, try to remember that there are but a very few fashionable authors. They are as follows: Mrs. Wharton, Colonel Mann, Mrs. Glyn, Robert Hichens, F. Peter Dunne, John Fox, Jr., and Billy Baxter.

At a dinner a gentleman sitting beside a débutante should congratulate her upon her début, and, in a few well-chosen words, should discuss the usual débutante topics—i. e., platonic love, banting, Ethel Barrymore, French dressmakers, John Drew, the relative merits of Harvard and Yale, love at first sight, the football match and the matter of her great personal beauty and charm.

Try always to remember that the chief and most interesting topics of conversation are herself and yourself. Serious topics are very properly deemed out of place in society.
