Mr. and Mrs. Brown lived in a house near London. They had only one child and he was very young. Mr. Brown often came back home from work very late when his wife and child were asleep. He usually opened the front door with his key and came into the room quietly. One night he forgot to bring his key. He had to ring the doorbell (门铃), but his wife didn't wake up. He rang it again. Again nothing happened. Then Mr. Brown knocked at the bedroom window and even shouted loudly. Still his wife didn't wake up. He thought for a moment. At last he had an idea. Then he began to speak like a small child. “Mom!” he said. “I want to drink some water.” His wife woke up right now and opened the door for him.
