100. Forgetfulness is a breach of etiquette. It is impossible to be polite without cultivating a good memory. The absent or self- absorbed person who forgets the names of his next-door neighbors, recalls unlucky topics, confuses the personal relationships of his personal friends, speaks of the dead as if they were still living, talks of peole in their hearing, and commits a hundred such blunders without any malevolent intention, is sure to make enemies for himself, and to wound the feelings of others. Carelessness, carried to a certain pitch, becomes unchristian. "It is not well," says an old proverb, "to talk of the gallows to a man whose father was hanged." Some persons are so notoriously absent or forgetful, that their friends will say of them: "We must not tell B---; he is certain to tread on somebody's corns. We must ask him some evening when we are alone." END
