　　One foolish question I can't stand is "How do you feel? ". Usually the question is asked of a man on the go-a man hurriedly walking along the street, or busily working at his desk. So what do you expect him to say? He'll probably say, "Fine, I'm all right. "But you have put a bug in his ear-maybe now he's not sure. If you are a good friend, you may have seen something in his face, or his walk, that he overlooked(忽略)that morning. It starts him worrying a little. The first thing you know, he looks in a mirror to see if everything is all right, while you go merrily on your way asking someone else "How do you feel? "

　　Every question has its time and place. It's perfectly acceptable, for example, to ask "How do you feel? " if you're visiting a close friend in hospital. But if the fellow is walking on both legs, hurrying to take a train, or sitting at his desk working, it's no time to ask him that silly question.
