While I walk at night, cars pass me. Typically I am in the darkness while walking and my eyes adjust to the ambient light of distant street lights and the moon half visible through a scrim of faint clouds. But then a car arrives. It is loud and throws light. I am nearly blinded even though I can make out the pale faces of passengers staring at me. I can see they can’t really make out what I am — they glance at me with unfocused eyes and then they are gone.
