C
    An old farmer spent all his time on his farm in the country, far from the city. One day he decided to visit the big city. Everything there was new and strange to him.
    The old farmer visited a lot of interesting places in the city.
    He went into a large tall building and saw a lift. When he watched, an old woman got into the lift and closed the door. After a while, the door opened again and a very beautiful young girl came out.
    The old farmer was very surprised. “What an interesting little room!" he said to himself. “It's magic (魔术) ! It can change an old woman into a young girl. The next time I come here, I'm going to bring my wife to take the lift.”
