There was a man who had a little boy that he loved very much. Every day after work the man would come home and play with the little boy. He would always spend all of his free time playing with the little boy.

One night, while the man was at work, he realized that he had some work to do for the evening, and he couldn’t play with his little boy. But he wanted to give the boy something to keep him busy. Then he saw a magazine with a large map of the world on the cover.

He got an idea. He removed the map, and then tore (撕) it up into small pieces. Then he put all the pieces in his pocket. When he got home, the little boy was ready to play with his dad. The man said he had work to do and couldn't play just now, but he took out all the pieces of the map and spread (撒)them on the table. He said it was a map of the world, and by the time he could put it back together, his work would be finished, and they could then play.

About half an hour later the boy came to the man and said, "Okay, it's finished. Can we play now?"The man was surprised, saying, "That's impossible. Let's go see." And sure enough, there was the picture of the world; all put together, every piece in its place. The man said, "That's amazing! How did you do that?" The boy said, "It was simple. On the back of the page was a picture of a man. When I put the man together the whole world fell into place."
