I remember standing on a street corner with the black painter Beauford Delaney down in the Village, waiting for the light to change, and he pointed down and said, “Look.” I looked and all I saw was water. And he said, “Look again,” which I did, and I saw oil on the water and the city reflected in the puddle. It was a great revelation to me. I can’t explain it. He taught me how to see, and how to trust what I saw. Painters have often taught writers how to see. And once you’ve had that experience, you see differently.
