Mr. and Mrs. Brown lived in a small house near London with their child. Sometimes Mr. Brown came back home from very late, when his wife and the child were asleep. Then he opened the front door of his house with his key and came in very quietly.
One night, he came home at midnight. He lost his key, so when he arrived home, he rang the doorbell. Nothing happened. He rang it again. Again nothing happened. Nobody moved inside the house. Mr. Brown knocked at the bedroom window, he spoke to his wife, he shouted, but she did not wake up. At last he stopped and thought for a few seconds. Then he began to speak like a small child. “Mummy!” he said, “I want to use the bathroom!” He spoke quite quietly but at once Mrs. Brown woke up. Then he spoke to her, and she opened the door for him.
