They Mixed up Everything

Three
young men came to a little station in the country and asked when the train to
London was leaving. They were told that it was leaving at eight o’clock. “Oh, we have a lot of time,’ said one of them.
Let’s go to the bar and have a drink. So they went to the bar, took a drink.
They forgot about the time and when they came to the platform their train had
left. They saw the station master on the platform. They went up to him and
asked, “When is the next train to London, please?” “Trains to London leave
every hour”, said the station master.            “Oh,
all right,” said the three friends, “We
have a lot of time. Let’s go to the bar and have another drink”. They went to
the bar and forgot about the time again. So when they came to the platform they
didn’t see the train. It had gone. “The last train to London will leave at ten
o’clock and if you miss it, you will have to wait until the morning”, said the
master.      “Oh, it’s O.K.”, said the
young men and went to the bar again. Of course they forgot about the time again
and when they came to the platform the ten o’clock train was just leaving. They
rushed along the platform trying to catch the train. Two of them ran very fast
and managed to jump on the steps of the last carriage. But the third man
remained on the platform.

When the master
Approached to him he was very surprised that the man was laughing. He laughed
till he cried and couldn’t stop. “What’s the matter with you? Asked the station
master. “Why are you laughing?” “Oh,” said the young man when he at last was
able to speak, “Did you see those two idiots who jumped on the train? They
mixed up everything! It was me who was going to London. They had only come to
the railway station to see me off.”
