Some mornings I wake up an hour or so early. I will get up and go into the living room, turn on a lamp and go back to bed, leaving the bedroom door open.
When my alarm clock wakes me up again, I will open my eyes and see the glow from the lamp in my hallway. For one very comfortable second I believe there is someone else in my apartment. Something to greet me, other than a cold kitchen floor and a droning refrigerator.
