Granny is dying and the story is told through her semi-conscious mind. The fact that her bones are "loose" and the doctor is "floating like a balloon" are indicative of the way her mind is working. Nothing seems quite real because of her closeness to death. This also is characteristic of the disjointed way Granny is telling the story. She floats through a seemingly unconnected set of memories that the reader must put together in order to understand that Granny is still trying to come to terms with the fact that she was "jilted" at the altar many years ago. Even though she lead a productive life and even married another man, the "jilting" still haunts her. Thus, the story also feels loose and somewhat disjointed unless we look at it from the perspective of a woman who, at death, has still not come to terms with one event in her life.
