27. Utter not base or frivolous things among grave or learned men; nor
introduce deep subjects or difficult questions among the ignorant; nor
things hard to be believed.
28. Jest not where none takes pleasure in mirth; laugh not loud, nor at
all, without occasion. Deride no man’s misfortune.
29. Speak not injurious words, neither in jest nor in earnest; scoff at
none, though they give occasion.
30. Be not forward, but friendly and courteous; the first to salute,
hear and answer.
