Late one night, Catherine Ryan Hyde was driving in Los Angeles. In a dangerous neighborhood, her car caught on fire. She got out. Three men ran toward her. She immediately felt afraid of them. They didn't hurt her, though. They put out the fire and called the fire department. When she turned to thank them, they were gone. Years later, that event became the subject of her novel called Pay It Forward. She never forgot that event. In the book, a teacher asks his students to "think of an idea for world change and put it into action." A boy named Trevor suggested doing kind acts for others. They used his ideas. Trevor's idea works like this. Someone chooses three people and does something nice for each one. In return, the recipients of that favor must do favors for three more people. In 2000, the novel inspired a movie.
