The story about the thorn map of the world
One day Dad came back home and was really tired. But his son couldnt't understand it, willing to play. The man, however, wanted a break to eat something and change the clothes. He asked his son to do a difficult but responsible task. Dad gave the boy the torn map of the world and asked him to put the map right.
Surprisingly, in exactly ten minutes the son was back with the map in a perfect condition.
