Perimeter breach

The floor trembled—heavy, mechanical hum approaching fast! That robotic vacuum turned the hallway corner at full throttle. No cover nearby, just an open rug zone. I bolted for the baseboard, grabbed a discarded plastic AA battery casing, and wedged it under the door wedge to secure an escape route. It brushed right past my boots, bristles spinning wildly! Heart was hammering, but the perimeter held. We're clear for now.
