4518. Speak not of doleful things in time of mirth, nor at the table; speak not of melancholy things, as death, and wounds; and if others mention them, change, if you can, the discourse. Tell not your dreams but to your intimate friend.
4519. Break not a jest where none takes pleasure in mirth; laugh not aloud, nor at all without occasion. Deride no man's misfortune, though there seem to be some cause.
4520. Speak not injurious words neither in jest nor earnest; scoff at none, although they give occasion.
4521. Be not forward, but friendly and courteous; the first to salute, hear, and answer; and be not pensive when it is a time to converse.
