★★★★ Sun! Unimpeded sun shone on the apartment building across the way, and the sky was cloudless. The ten-year-old, from the couch, found an angle at which the half-moon was visible, bright with its own reflected share of sunlight. What were the properties of this sun, again? It was blinding, when one walked facing into it, so that black surfaces were white and oncoming people were unrecognizable. It was even painful, by midday, sinking into bare skin with a sting like a razor burn. It was inviting, drawing the feet back outside, drawing the eyes upward to where there were now brilliant white patches of cloud with blue rifts curling back and forth in them. And it was brief—by the workday’s end, already lost to view.
