I must have lain there longer than I thought. Although I definitely remember getting up a few times to eat and use the bathroom, I slept a lot. Still, I was reasonably sure it was all in the same day. My moments of wakefulness didn’t seem very long. But with the window covered and the sliding door between the kitchen and the main room pulled closed, the room was just an infinite stretch of night, and I didn’t invite day. Each time I ventured into the kitchen, it was dark in there too, which just reinforced my assumption. So when I heard a knock on my door, it completely threw me.
I found the door by following the sound, only to stub my toes on the shopping bags I’d left right in front of it. I nudged the bags aside with my foot and just pulled the door open without checking the peephole.
