Superman
Every morning, Little Ray insisted that his mother pin a red bath towel to his t-shirt. Then, in his imagination, he became Superman, and filled his summer holiday with adventure and daring. When Autumn came, and Ray started kindergarten, the teacher asked his name. "I'm Superman," he answered.
The teacher smiled and looked at Ray's mother. "Your real name, please." And again, Ray answered, "Superman."

Ray looked around the room, leaned closer, and said in a hush, "Clark Kent!"
