Several summers ago, Joe Smith, a coach(教练)of a football team, and his family were spending their holidays in a small town. One rainy afternoon, it was impossible for them to go out to do something interesting, so the family decided to go to cinema. Joe, his wife, and their three children walked soon to the town's only cinema, bought tickets and went into the hall. The lights were still on, and there were just six other persons there. As Joe entered, some of them saw him and started chapping(鼓掌).
Joe gave them a smile and turned to his wife. "Aha, I can't believed they know me and I'm getting a warm welcome here," he guessed. "They saw my games on TV."
They sat down and then a young man came back and gave out his hand. "Thanks a lot," said the coach. "I just can't believe you know who I am." "All I know," replied the man, "It is that they would not show the film until at least ten people bought tickets."
