We were sitting in tightly arranged desk pods in the class room as we worked on our assignments. There was a tense feeling that something bad was about to happen when a sudden beeping sound came from the front of the classroom. Those of us close to the source of the noise quickly got up and moved to the back of the room. A security guard walked up to the chalkboard and picked up the offending radio clock from the floor. He yanked out the battery from the device before a break was announced for the class. I needed to use the restroom.
