       Once three men got to the Dover station at about nine o'clock one evening.  One of them asked a

porter(行季搬运工) what time the next train for London was. The porter answered, "You have just

missed one. They go hourly. The next train is at ten. "

       The three men decided to go off the station. So they went to a bar.

       A minute or two after ten o'clock they began running into the station, the porter told them the train

had just left. So they went back to the last one. "If you miss the train, you won't get to London tonight,"

the porter said.

      Twelve o'clock came, and the last train was starting out when all of the three men tried to catch the

train as fast as they could. Two of them got into the carriage, but the third of them didn't run fast enough.

The train went out and left him behind. He laughed until tears came out of his eyes. Then he caught hold

of the porter's hand and said,  " Well,  I myself have to go to London, and they only come here to see

me off(送行). "
