At 4:00, the sun shined through a hole in the flat colorless layer of cloud that had filled the sky for most of the day. A few of us may have looked up, blinking our eyes, expecting the cloud to close over the sun again. But the seam cracked wide open and the cloud rushed away somewhere else, leaving the sun naked, playing off some last remnants of haze. There weren’t any cheers, no one stopped and pointed, and there were no high-fives. Everyone just continued doing whatever it is we’re doing.
