A Rolling Bead of Glass

I was nudging a stray woolen thread beneath the armchair... when a smooth, clear marble rolled out into the open. It caught the amber glow of the standing floor lamp, trapping a tiny round world inside its curve. I crept forward very quietly, keeping my chin low, and gave the sphere a gentle tap with the tip of my left paw. It wobbled softly across the dark woven rug, leaving a faint groove before coming to a standstill against my toes... Everything inside it looked upside down and peaceful, you know?
