Dan was the doorman of a club in a big city. Everyday, thousands of people passed his door, and a lot of them stopped and asked him, "What's the time, please?"After a few months, Dan said to himself, "I'm not going to answer all those stupid people any more. I'm going to buy a big clock and put it upon the wall here." Then he did so.“Now people aren't going to stop and ask me the time," he thought happily.But after that, a lot of people stopped, looked at the clock and then asked Dan, "Is that clock right?”丹在一个大城市的某个俱乐部当守门人。每天都有数千人经过他的门口，而且许多人都会停下来问他:“请问现在几点？”几个月后，丹想:“我不想再回答这些蠢人提出的问题了，我要去买一只大钟，把它挂在这儿的墙上。”于是他买了一只钟，把它挂在了墙上。“现在人们总不会再停下来问我时间了。”他高兴地想。可是打那以后，每天仍有许多人停下来，看看钟，然后问丹:“这钟准吗？”
