Should a person enter the room in which you are conversing, and the conversation be continued after his arrival, it is only courteous to acquaint him with the nature of the subject to which it relates, and to give him an idea of what has passed.

Be cautious in relating anecdotes. Unless you can tell a story with ease and effect, it is better not to attempt it, and, above all, do not mimic the peculiarities, infirmities, or short-comings of others in general society. You may give offense to some one present who is a friend of the person caricatured, and in any case such a proceeding is not commendable.

Do not speak of what passes in a house that you are visiting. To do so may often give great offence.

You need not tell all the truth unless to those who have a right to know it all. But let all you tell be the truth.

Do not offer advice unless you know it will be followed, and carefully beware how you advise an angry or an opinionated person. As a rule, advice not asked is not welcomed.

Be cautious as to asking questions. The reply may be very embarrassing to the person of whom the question is asked.

Do not volunteer information, especially in public; but be very sure you are correct in what you state as facts.

Do not sit dumb in company, but bear your share in the general conversation. Do this with modesty and self-possession, neither thrusting yourself forward, nor hesitating where you should speak. It is better to be a good listener than a good talker, yet it is a duty to take your part in entertaining.

It is not necessary to express your opin ions upon all subjects; but if you give utterance to them, do so fearlessly, frankly, and with courteous regard for the opinions of others. The greater your learning, the more modest should be your manner of expressing it.
