One day, Mr White came home very late. He looked for the key to the door, but can't find it. He lost his key. He rang the bell, but nothing happened. He did it again. Nobody moved inside the room. Mr White knocked at the bedroom window, he spoke to his wife, he shouted, but she didn't wake up. At last he stopped and thought for a moment. Then he began to speak like a small child. He said, “Mother, I want to go to the toilet.” He spoke quite quietly, but at once Mrs White woke up. Then he spoke to her, and she opened the door for him.
