Scott walked into the almost empty office. One worker was typing at his computer. The worker smiled and said, "How's it going?" Scott didn't know the worker. He said Hi without smiling. He sat down at a nearby desk. His back was to the worker. Scott was waiting for his agent to show up. He looked out the window. It was a sunny day. He heard the worker typing. The typing got louder. A minute later, he heard the worker whistling. The whistling got louder. Scott started singing. He sang, "She loves you, yeah, yeah, yeah!" He sang it five times. Then he stopped. He turned around. The worker was looking at him. The worker was silent. "That's my favorite song," Scott said. "Whenever I hear whistling, I sing that song. I don't want someone else's song stuck in my head. It's hard to get rid of someone else's song."
