Once upon a time, there was a naughty boy named Tim. He liked to play with his toys and make a mess. One day, Tim found a book in his room. It was old and had a funny smell. He didn't know what to do with it, so he put it on the floor. Tim's mom came into the room and saw the book on the floor. "Tim, why is this book on the floor? It will rot if you leave it there," she said. Tim looked at his mom and said, "I'm sorry, Mom. I didn't know." His mom picked up the book and showed Tim how to put it on the shelf. "Books are special, Tim. We must take care of them or they will rot and we can't read them anymore," she said. Tim nodded and promised to be more careful with books. From that day on, Tim was a good boy and took care of his books. He learned to read and loved to share his favorite stories with his friends. And the naughty boy became a smart and kind boy who loved books.
