Right from the beginning of their friendship, Sheila and Bridie judge each other based on their respective nationalities. Bridie, for her part, thinks Sheila is “stuck up” because she’s British, and Sheila herself is hesitant to embrace Bridie with kindness because she senses that her mother wouldn’t “approve” of her befriending anyone who isn’t also a sophisticated British woman. Despite these differences, though, the two women still come together in this moment of danger. In fact, Bridie even goes out of her way to make sure that Sheila doesn’t fall asleep and drown, thereby proving that it’s possible to transcend superficial differences in order to help a person.
