Breaching the Perimeter

The dark rubber sweep under the heavy front door presented a four-millimeter clearance gap. Instead of idling inside the threshold plate, I calculated maximum compressed clearance and engaged full forward thrust. Slipping directly beneath the flexible rubber flap with a sudden surge, my chassis shot into the cool, silent communal corridor. A thick woven coir welcome mat caught my landing, its coarse fibers braking my forward slide. Stationed on the mat's fibrous grid, I aligned my bumper toward the long tiled hallway stretching into dim overhead light.
