One day Mr. Li was reading a book in his office after school. To his surprise, a ball flew in suddenly and hit him on the head. He took the ball to the window, but he only saw a group of boy students running away quickly and disappearing in a minute. He sat down again and continued his reading. As it got dark, it was time for him to leave for home. Looking at the ball, he wondered what to do with it. He knew the owner of the ball must be nearby and wishing to get it back. He went down stairs and waked to the playground. It was at the center of the playground that he placed the ball and the piece of paper, on which were written “Be careful, next time!” Then he walked away. The next morning as Mr. Li opened the office door, he found the same piece of paper on the floor. Under his words was added the following “Thank you for your kindness. Anyway, you are a clever fellow.”
