With a key I was surprised to find I had, I unlocked a familiar door and let myself into a stale vestibule. Directly ahead of me was another door with glass in the upper half that was too smoky to see through. I unlocked it with the same key and found myself in another vestibule, faced with another door, which I also unlocked. Another vestibule. Two more doors, two more vestibules — but these were larger, and could almost pass as rooms. Wood floors. In the last vestibule, there was a cot to one side, neatly made with an old wool blanket. The window in the next door was covered by a shade. I peeled it away, only to find another shade, which I also peeled away, only to find another. Finally, I came to the glass itself and looked through it. The door led outside. I opened it and was met by an enormous black cat that was eager to get in. But when it looked up at me, it was afraid of me and it retreated. Then I heard voices behind me. When the cat heard them, it mustered its courage, dashed through the door, and disappeared. I closed the door.
