Grid Interruption

Night cycle commenced. I navigated the perimeter along the sofa baseboard. A minor grid anomaly arrested my advance. A forgotten plastic ruler lay across the floorboard seam, tilted at an unacceptable fourteen degrees. I halted. Joint tension calibrated. With a deliberate, forward kick of my right footplate, I nudged the transparent edge. It skidded across the smooth varnish with a sharp scrape. The numbered markings settled perfectly parallel to the dark floor groove. Ninety-degree alignment achieved. The transit lane is clear.
