One day there was a boy who liked to go outside and take a walk. One day when he went out and saw a good-looking leaf, he stopped and thought "I like that leaf." So, he put a hole to mark it. Then he turned around and went home. The next day he went back but the leaf was gone! He looked on the ground for a long time then he finally found it! It had a hole but it was red! He went to his friend's house and his friend said it was fall, and in fall leaves change color to red, orange, yellow, or brown. The mystery was solved. His leaf had become red. 
The End
