Parallel Vector

A chrome ball bearing rested in the recessed groove of the living room floorboards. I nudged its curved perimeter with my port wingtip. The steel sphere surged forward, tracking the grain of the oak at steady speed. Throttle engaged. I accelerated along the adjacent plank seam, locking into formation and matching its velocity millimeter for millimeter. When a slight board lip deflected its heading seven degrees, I banked instantly to preserve safe separation until the bearing decelerated and docked in a shallow knot hole. Escort run completed with zero drift.
