Out on the "rosy-colored porch" after dinner, Daisy tells Nick that they do not really know each other very well despite the fact that they are related. She accuses him of missing her wedding, and he politely reminds her that he was not back from fighting in the war yet. She tells him, "Well, I've had a very bad time, Nick, and I'm pretty cynical about everything." It's an incredibly ironic statement to make to a man who fought in the worst war known to humankind. Such a statement seems relatively inexplicable given Daisy's tremendous luxury and advantages in life; however, she does have a rather stupid and unfaithful husband, and she is, evidently, well aware of his philandering habits. She claims that "everything's terrible" and that "'Everybody thinks so—the most advanced people.'"
When Nick tries to turn the conversation to something a bit happier, namely, Daisy's daughter, she says, "I'm glad it's a girl, and I hope she'll be a fool—that's the best thing a girl can be in this world, a beautiful little fool." Daisy does seem pretty cynical, but perhaps she is also somewhat realistic. She must believe that ignorance is bliss, so she hopes that her daughter will be a fool because then the girl might have a reasonable chance of being happy—unlike her mother.
