I wanted to be with the people around me in the darkness. The walls between people are thin here, and if I listen quietly, I hear what is going on. Greenwich Village is like that too. Not just being close—because I don’t feel it in a crowded elevator or on the subway during the rush—but on a hot night when everyone is out walking, or sitting in the theater, there is a rustling, and for a moment I brush against someone and sense the connection between the branch and trunk and the deep root. At such moments my flesh is thin and tight, and the unbearable hunger to be part of it drives me out to search in the dark corners and blind alleys of the night.
