'Be watchful against levity. C. is a good, devoted fellow, but naturally
an incorrigible joker. It may not hurt him much, because it is his
nature; but it will hurt you if you give way to it. It hurts nearly
everybody.
Watch! Don't descend to buffoonery. While you become all things to win
some, don't forfeit your natural self-respect and the dignity of your
position as a servant of Christ.'
