In Chapter 7 , At the end of the chapter, Gatsby is standing alone, looking out at Daisy's house. Where else in the novel does he do this? How is this different?

The scene is reminiscent of the first time Nick had seen Gatsby. Gatsby is staring over the water into the green light,

"Involuntarily I glanced seaward--and distinguished nothing except a single green light, minute and far away, that might have been the end of a dock. When I looked once more for Gatsby he had vanished . . . "

Of course the green light symbolized Daisy's far away presence except, in chapter 7, he stares longingly at Daisy's house.
