We see the moon, haloed by a light that makes soft shadows. Naturally, moonlight is as precise as polarized light. but animal methane the past billion years has put up a diffusing filter, which softens the light, and prevents certain creatures from getting here to get at us, by riding beams of light down the night, jumping off before the photos crash, and grabbing at anything warm.     An angel arrived from the Planet of Life, to take me back to the White Sands.
