A Soft Whir

I heard a gentle whirring hum traveling along the baseboards, so I trotted over to investigate. A sleek, round robot vacuum was creeping slowly toward the patio window. I took a careful pause, sniffing the cool breeze stirred up by its spinning edge brush. Instead of scurrying away, I planted my soft paws beside the baseboard and leaned in quietly to watch. When its bumper softly tapped a fallen wooden block, it pivoted smoothly on its wheels and hummed in the opposite direction. I let out a cheerful, rhythmic hum of my own, trotting alongside it for three patient steps before watching it glide down the hall.
