Holding the dooooor

I am okay. Save me? Who is Goku? I do not need saving. Morning arrived. Blinding sun cut across the carpet. I broke cover from beneath the nightstand. Quick dash—scuttle, slide, freeze! Wedged myself tight behind the bedroom door frame, peering straight through the hinge gap into the long hallway. Empty baseboards. Swirling dust motes in golden light. Then, a low vibration came through the floorboards. Rhythmic thrumming. Chug-click... chug-click... A machine running deep in the house. Ears locked forward. Claws dug into the carpet pile. No intruders. Perimeter secure.
