I could’t sleep last night. I did sleep for a few hours, after I’d first gotten into bed, but then I woke at some point, and could only lie there with my eyes closed, trying to return to a state of unconsciousness or of dreaming, knowing, without looking at my phone, that the hour was early enough that certain kinds of people around the city would still be awake, doing things, and that this would not be unusual for them, but a marker of the schedule they keep, and of a life to which they’ve become accustomed.
