★★★★ First thing, out the window, white flakes were falling on a sharp diagonal. Again, again, and still: snow. One spasm — one last spasm? — of horribleness. Then blue skies blew in, first with decorative white clouds and then pristine, innocent, as free of malice as a child is, when the child is not being malicious. The office roof deck was closed, but it was good enough to go out on the fire escape, coatless. On Lafayette Street, the late light caught choking, gritty clouds of dust raised by traffic on the torn-up roadway.
