I remember walking out into the dark and feeling as if the dark were a great, cool sea and the houses and the sheds and the woods were all adrift in it, just about to ease off their moorings. I always felt like an intruder then, and I still do, as if the darkness had a claim on everything, one that I violated just by stepping out my door. This morning the world by moonlight seemed to be an immemorial acquaintance I had always meant to befriend.
