Jon Gibson, Please Report to Room 21

"Jon Gibson, please report to Room 21," the PA shouted suddenly. Jon's eyes went wide. Why were they announcing his name over the PA system? He looked around the room, noticing that everyone was looking at him, probably wondering if he was in trouble. He was kind of wondering the same thing himself. As he thought about it, there was something odd about the announcement. The person making it said that he should go to Room 21. But that room was in the basement. There were only a few offices down there, and no classrooms. "Get to it, Gibson," his teacher said, breaking him out of his thoughts. He slowly stood up and left the room.
