I think the reader can most likely conclude that the speaker: Recognizes and respects her grandmother's social position
During her bath, the narrator slowly understands her Grandmother position as she grew older. If we pay attention to our society, we will see that the elderly keep losing power as they got older. They used to be listened by their children but after a certain age, the position is reserved. The children took more power over their old parents.
hmm.. the author used a metaphor so you would have a better understanding on how the horrid pain in their left side felt. metaphors allow creativity and can paint a clearer picture of what you describe. they help express certain emotions and can help you better understand something.
