Miss Manners corrects only upon request. Then she does it from a distance, with no names attached, and no personal relationship, however distant, between the corrector and the correctee. She does not search out errors like a policeman leaping out of a speed trap. When Miss Manners observes people behaving rudely, she behaves politely to them, and then goes home and snickers about them afterward.
