When a friend makes a mistake, don't rub it in, rub it out. We should work harder to be what we ought to be than to hide what we are. Many wise words are spoken in jest but they can't compare with the number of foolish words spoken in earnest.

Wisdom is knowing when to speak your mind and when to mind your speech.
