The Stopwatch.

The alarm rings, rousing you up for school. You wake up, grouchily stumbling to the bathroom. You wash your your face, and walk back to your bedroom. Then, as your eyes adjust, you see a strange parcel on your table. You open it, a silver watch rests inside. You read the paper tied to it.

"Dear, Timestopper. The Device you hold in your hands allows you to stop time. Press on the screen to stop time and again to resume time. Have Fun. -Sinr Corporation.

You look at the watch, then clasp the metal band over your hand, Fits perfectly. Although you think it's a joke, you press the screen anyway. Suddenly, everything feels deadly silent. Usually, there would be small insignificant sounds that you would block out. But now, there was none. None at all...

You open the door cautiously, and peek out.
