I.                  Balzac and the Thief

      The famous French writer is a known as a
great humorist. Here is one of his stories.

      It happened at night, when Balzac was
lying in bed awake. He couldn’t sleep as it was quite light in the room because
of the moonlight.

     Suddenly Balzac heard some noise and he
saw a man enter his room. He moved very carefully trying not to make any noise.
Balzac realized that the stranger was a thief. He understood that the thief was
looking for money.

      Balzac began to laugh very loudly, but
the thief did not get frightened and asked the famous writer why he was
laughing.

       Balzac told the thief that he was very
sorry for him. The famous writer had no money. He often could not find a penny
in his desk. The thief was very much surprised. He thought that a great writer
must have a lot of money. He was disappointed and left the room at once.
