After John’s first wife died, he gets married again. His second wife was more younger than he was and they often quarreled. John once came home lately after work, his wife said to him that he had waited for two hours. She was too angry that she gave him a push, which made him fall down the stairs so he is old and weak. When Steven, one of John’s neighbor, heard the noise, he was eager to know which was happening. He came John’s front door and knocked. “What’s happened?” he asked. “My coat fell down the stairs,” John answered. When the neighbor said a coat wouldn’t make so many noise, John answered, “Of course it would if I was inside it!”
