Sal’s newfound ability to recognize her own story reflected in Phoebe’s hearkens back to the beginning of the novel, when she said that Momma’s story is hidden behind Mrs. Winterbottoms’ (like the fireplace hidden behind the wall). Phoebe’s story is helping Sal come to terms with the fact that Momma left, and that she isn’t to blame for Tulip’s death or for Momma leaving. Perhaps Momma, like Mrs. Winterbottom, was just unhappy and needed alone time. It’s also a mark of Sal’s growing maturity that she recognizes that mothers, including her own, are their own people—they don’t exist solely to serve their spouses and children. Finally, Sal’s thought about hoping for the best ties in with the story of Pandora’s box and with the idea that people can choose not to let “birds of sadness” nest in their hair. Just as it’s always possible for disaster to strike, it’s also possible that things will improve—and people can choose whether to fixate on tragedy (as Phoebe does) or hold onto hope.
