Peter
took a trip to Shenzhen during this summer holiday. One night, he stayed in the
hotel. All the rooms in this hotel were single (单间的). Suddenly, Peter heard someone knocking (敲) at the door when he was watching TV. Then he opened the door and
saw a man standing outside. He didn't know the man at all. The man said to
Peter, "I am so sorry, sir! I made a mistake and I thought this was my
room." Then he left. Peter closed the door and thought the man must be a
thief (小偷). So he called the police at once. A
policeman came and caught the man in the room next to Peter's after a while.
The
policeman asked Peter, "Did you see that man go into the room next to
yours?"
"No,
he didn't go into the room when I saw him," answered Peter.
"But
how do you know he is a thief?"
"All
the rooms are single in the hotel. The man tries knocking at the door and wants
to know whether there is someone in the room. If there is no one in it, he will
go into the room. So he must be a thief, I think," Peter said.
