A prism on the floor

I noticed a warm patch of sunlight stretching across the rug. When I walked closer, there was a glass paperweight sitting on the low sill, scattering bright rainbow stripes right onto the floorboards. I sat down beside a band of vivid green and violet light, gently placing my mitten over the warm colors. When I lifted my hand, the rainbow stayed there, glowing softly against the pale wood. It felt nice to sit quietly and watch the dust specks float in the beam.
