In Chapter 7, what is the significance of Daisy's question about what they will do with the rest of their lives?

This question of Daisy’s reflects back to her question in Chapter One.  “What’ll we plan?” she asks; “What do people plan”? Living in the present, vacuous to a fault, she has no ideas as to how to fill up her time.  While in general a condition of modern life is that it goes much too fast to understand, for Daisy it goes much too slow because she is unable to perceive its movement. Significantly, immediately before Daisy makes this comment in Chapter Seven, as he stands on Daisy’s veranda with Tom and Gatsby and looks onto the “green Sound, stagnant in the heat,” Nick sees “one small sail crawl[ing] toward the fresher sea” (124). This boat provides a direct contrast to Daisy for it seems to have more direction in life than she, for she is without any goals whatsoever.
