The Great Gatsby, sophisticated

She thinks she is sophisticated because she has seen so much of the world that other people have not seen. She is blase in the sense that she thinks there is little left to see, and she finds every day dull because nothing seems to cause her any excitement. She has this huge insecurity that makes her want to be "one up" on all the people around her. In this regard, she has picked up on Tom's attitudes about many things; he too feels that he is so much better than everyone around him. Daisy, in many ways, has no opinions of her own, only those of the most "advanced people." She is not particularly cultured (mostly because she does not care about what she has seen), and she is not culturally aware.
