Mrs. Costello objects to the Millers and mocks their pretensions for two reasons: first, since Mr. Miller made his money rather than inheriting it, the Millers represent “new money,” and second, they are vulgar. The Millers are vulgar, especially Daisy. She tells Winterbourne about having grilled the hotel chambermaid about his aunt, which is a vulgar thing to do, let alone to admit to Winterbourne. Daisy’s speech habits are a clue that James intends us to regard her critically. She talks endlessly and monotonously about herself, with frequent recourse to expressions such as the phrase “ever so” that undereducated Americans thought were “refined.” Daisy seems to regard every thought that runs through her mind worth expressing, which is an extraordinary kind of egotism. Daisy is also silly and vapid, and even the atmosphere of the castle at Chillon, with its historic and literary associations, fails to distract Daisy from the business of flirting. Her focus remains trained on the trivial and personal, her own and Winterbourne’s “tastes, habits, and intentions.” Daisy’s almost infantile approach to conversation seems to be a symptom of her larger inability to adapt to her surroundings.
