Perimeter Survey

I advanced four deliberate paces past the edge of the notebook, testing the stability of the terrain. A heavy ceramic mug obstructed direct line of sight toward the desk boundary. Instead of circumventing it hastily, I placed one hand against the smooth, cool glaze to assess its mass. Firm. Unyielding. Using its bulk as structural cover, I scanned the expanse of the room ahead. The floor lies several feet below, quiet and vast. Our perimeter holds.
