A driver stopped his car on a street side to have a rest. As he lay down in the seat and closed his eyes, a person came up and knocked(敲) at the window to ask the time. The driver opened his eyes and looked at his watch: “It’s 8:05,” he said. Then he went to sleep again. But soon he was waken up(被叫醒) again because a second person was knocking at the window. “Sir, do you know the time?” he asked. The driver looked at his watch again, and told him it was half past eight. In this way, the driver thought he could not have a good rest, so he wrote a short note(纸条) and stuck(贴) it on the window for all to see. It said, “I don’t know the time.” Again, he lay down in the seat for his sleep. A few minutes later, a third person came and began to knock at the window, “Hey, sir,” he said. “It’s a quarter to nine.”
