A train stopped at a small station. A man looked out of the window and saw a woman who was selling cakes. People from the train were buying them. The man wanted to buy a cake, but the woman was standing far from the window. It was raining, and the man didn’t want to go out in the rain. Suddenly he saw a boy who was walking on the platform(站台) not far from him.

“Come here, boy!” the man said. “Do you know how much those cakes cost?” “Five cents for each,” the boy answered. The man gave the boy ten cents and asked him to buy two cakes. “One for me, and one for you,” he told the boy. A few minutes later, the boy came back. He was eating a cake. He gave the man five cents and said, “There was only one cake.”
