Sal seems to decide on telling Phoebe’s story solely because she believes her grandparents will find it interesting. At this point, Sal doesn’t see storytelling as anything other than a method to entertain people, which is why she focuses on sensational, “exceptionally strange” elements like Phoebe’s mother’s disappearance and the “lunatic.” However, the reader knows from the previous chapter that after this trip is over, Sal will recognize that Phoebe’s story is like the plaster wall Dad chipped away at to reveal a hidden fireplace. In other words, she will come to see storytelling as a way to uncover hidden truths.
