The Ladies' Book of Etiquette, and Manual of Politeness

The art of conversation consists in the exercise of two fine qualities. You must originate, and you must sympathize; you must possess at the same time the habit of communicating and of listening attentively. The union is rare but irresistible. None but an excessively ill-bred person will allow her attention to wander from the person with whom she is conversing; and especially she will never, while seeming to be entirely attentive to her companion, answer a remark or question made to another person, in another group. Unless the conversation be general among a party of friends, confine your remarks and attention entirely to the person with whom you are conversing. Steele says, "I would establish but one great general rule in conversation, which is this-that people should not talk to please themselves, but those who hear them. This would make them consider whether what they speak be worth hearing; whether there be either wit or sense in what they are about to say; and whether it be adapted to the time when, the place where, and the person to whom, it is spoken."
