How does Granny change in the course of the story? Does she change at all? Is the story's major focus on Granny's thoughts (and lack of focus on other elements like plot or setting) a strength or weakness of the story? (the jilting of granny)

<<After his death, Granny changed. She had to fence in acres of land and act as a midwife and nurse. She thinks John would appreciate the way she kept nearly all her patients alive. She remembers lighting the lamps when her children were young.
