Oh dear friends

I cannot tell you how keenly sad I felt when the moon had passed to the other side of the sun and, though the earth had been transformed—subtly and perfectly transformed, shadows blurred and twisted into curves, the sunlight rendered almost green or maybe orange and somehow bright and dark at once—it became itself again and the shadows were again sharp-edged and straight and the light was again just light, the dark just dark, the space where light was not.
