Aunt Wang is ill. She is in the People's Hospital. Tony's mother tells Tony to take a basket of eggs to Aunt Wang. But Tony doesn't know the way.
On the way Tony sees and old man. The old man walks in front of him. He goes up and says, "Hi, old fellow..." But the old man doesn't answer him and walks on.
Tony gets puzzled (困惑的). Suddenly he understands (理解) why. It is not polite (有礼貌的) to say "old fellow" to an old man. Now he goes up to the old man again and asks, "Excuse me, Grandpa. Would you please tell me the way to the People's Hospital?" This time the old man answers. "Well, go along this street, and then turn left. It's just behind the post office."
