A Rolling Glass Marble

A tiny click echoed near the entryway... and something shiny rolled across the wooden floorboards. Taking cautious, pattering steps forward, I found a clear glass marble trapped in the shallow groove between the planks. I tapped it gently with the tip of my bill. It spun in place, throwing little specks of bright light onto the wall! Leaning down with my chest close to the floor, I pushed it with my beak, steering it along the straight line until it bumped softly against a folded cotton mat.
