In the evening, Anderson went downstairs for supper. He saw a blackboard. The names of all the guests were written on the blackboard. Anderson saw that the inn was full.There were no empty rooms. Anderson noticed that there was no room number 13.Thirteen is an unlucky number. Many people do not want to stay in a room with an unlucky number.When Anderson went upstairs to bed, he tried to unlock his door. It did not open. Then he saw that he had made a
mistake. It was the wrong room. The number on the door was number 13.He heard someone moving inside the room.'I'm very sorry,' he said and went to the door of room
number 12.Perhaps the servants sleep in room 13, Anderson thought. He decided to ask the landlord about it the next day
