I love to be outside as night falls. Whenever I can, I mark the transition from day to night by walking through quickly darkening streets and peeping into the neighboring houses. My neighbors and I may have nothing in common beyond the fact that the light of day is fading for us all, but when I pass by their uncurtained windows I leave traces; a wake of moving air, the sound of a footstep, or the impression of a familiar face to someone invisible to me. There is an intimacy to this repeated, glancing attention. As I stalk the last licks of light, I am sutured into the lives lived behind the windows I pass.
