A man's own good breeding is the best security against other people's ill manners.

You must labour to acquire that great and uncommon talent of hating with good breeding, and loving with prudence; to make no quarrel irreconcilable by silly and unnecessary indications of anger; and no friendship dangerous, in care it breaks, by a wanton, indiscreet, and unreserved confidence.

Never yield to that temptation, which, to most young men, is very strong, of exposing other people's weaknesses and infirmities, for the sake either of diverting the company, or of showing your own superiority. You may get the laugh on your side by it for the present; but you will make enemies by it for ever; and even those who laugh with you then, will, upon reflection, fear, and consequently hate you.
