A Perfect Fit

I pushed off from the carpet with one firm roll. Forward! Across the smooth floorboards I went. Ahead sat a neat wooden cubby on the lowest shelf, lined with three upright hardback books. A small gap waited right at the edge. I steered straight in. Bump! My soft round side pressed flush against the warm book spine and the wooden wall. Snug. Secure. Not rolling anywhere. It feels like my own private docking bay for the night.
