For lack of a coherent entry, I thought I'd ramble a bit…
I never quite found a way to believe that my little blue planet took the opportunity of wintertime to point away from the Sun, not until I looked up one icy, sunny winter day and saw the rainbows. Every year after that, they came back, like the ice, my silent friends of wintertime afternoons. Only in midwinter was the sunlight angled correctly to stream in through the picture window, where it would be refracted through the cut-glass panes of my mother's coffee table.
If you looked up, straight ahead, toward the kitchen, you would see the horizontal rainbows splayed against the ceiling. They would show up first as white globs of light, then sharpen into rainbows, and then quietly fade over the course of the afternoon.
On the days of ice storms, they gave me something else to watch besides the glass-sculpture world outside the window.
