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 man came up and knocked at the window to ask the time. The driver opened his eyes and looked at his watch. “It's 8 a.m.,” he said. Then he went to sleep again.
But soon he woke up because a second person was knocking at the window. “Sir, do you have the time?” he asked. The driver looked at his watch again, and told the man it was 8:30 a.m..
At this rate (照此下去), he could not have a good rest, so he wrote a short note and put it up on the window for all to see. It said, “I don't have the time.”
Again the man lay down in the seat for his sleep. A few minutes later, a third person came along and began knocking at the window. “Hey, sir,” he said, “it's a quarter to nine.”
