根据短文理解，选择正确答案。

    Mrs. Turner's telephone number was 3463, and the number of the cinema in town was 3464. People often made mistakes and telephoned her when they actually wanted the cinema.

    One evening the telephone bell rang and Mrs. Turner answered it. A tired man's voice came over the telephone, “At what time does your last film begin?” “I'm sorry,” said Mrs. Turner, “but you have the wrong number. This is not the cinema.” “Oh, it began twenty minutes ago? ” said the man. “I'm sorry about that. Well, goodbye.” Mrs. Turner was very surprised, so she told her husband. He laughed and said, “No, that wasn't a mistake. The man's wife wanted to go to the cinema, but he was feeling tired, so he telephoned the cinema. His wife heard him, but she didn't hear you. Now they will stay at home this evening, and the husband will be happy!”
