Mr Brown and his wife lived in a small house near London with their child. Mr Brown came back from his work very late. His wife and the child were asleep. He usually opened the front door of his house with his key quietly. But one night when he came home late, he lost his key. So when he reached his home, he rang the bell, but nothing happened. At last he had a good idea. He began to speak like a small child. “Mother!” he said, “I want to go to the toilet!” At once Mrs Brown woke up. Then he spoke to her, and she opened the door for him.
