Yesterday Tom played with a ball in the street. He threw the ball too hard, and it broke the window of a house and fell inside. A woman walked out with the ball and shouted at him. Tom ran away, but he wanted his ball back. Then he walked back to the house and said to the woman, "My father's going to fix (修理) your window soon." Then a man came. So the woman let Tom take his ball away. When the man finished fixing the window, he said to the woman, "Ten dollars, please." "But aren't you the father of that boy?" the woman asked. "Of course not," he answered. "Aren't you his mother?"
