I look at the glass partition that is set right at the tangent of the medical wing. I check my earphones, set right in my ear, and step several steps back, looking down at the tab screen—red light showing me the radius of the range of the motion sensor. I make sure I am right outside that range. I take out the circular device I managed to create that would deactivate the motion detectors and place the black metallic circular disc, the size of my palm, down on the ground. I slide it right at the center of the range where it would be undetectable. The detectors are as much body-heat based as they are motion-based; they sense something moving with the temperature of a body. It won’t be able to detect the disc—and slowly, a blue ray spreads across the radius of the motion detectors. The detectors blink red for a millisecond and then turn blue.

The tab shows the lines of code running and, at last, it blinks in little green words: ‘DEACTIVATED.’
