in the story the great gatsby how would you explain what the following quote means;

There were the same people, or at least the same sort of people.the same profusion of champagne the same many colored, many keyed commotion, but i felt an unpleasantness in the air, a pervading harshness that hadnt been there before, or perhaps i have mergenly grew used to it. grown to except west egg as a world complete to itself, with its own standards, and its own great figures. second to nothing because it had no conciensness of being so and now i was looking at it again,through daisys eyes it is invaribly saddening to look through new eyes at things apon which yu have expended your own powers of adjustment

In this quote from "The Great Gatsby," the narrator is reflecting on his experience attending parties at West Egg. The line "There were the same people, or at least the same sort of people" implies that the partygoers are familiar to him, and the setting remains unchanged.

The phrase "the same profusion of champagne, the same many-colored, many-keyed commotion" refers to the excessive opulence and chaos that characterized the parties at West Egg. This suggests that the atmosphere and festivities are consistent.

However, the narrator notices a shift in the air, describing it as "an unpleasantness," a "pervading harshness" that was not present before. This could be signaling a change in the mood or attitude of the people at the party. It could also suggest a growing familiarity or indifference on the part of the narrator, as he mentions that he may have "mergedly grew used to it."

The following sentence, "grown to except West Egg as a world complete to itself, with its own standards, and its own great figures," implies that the narrator has come to accept West Egg as its own distinct world, separate from reality, with its own rules and influential personalities. He feels that West Egg is second to nothing else, believing it lacks awareness or consciousness of being less significant.

The final part of the quote, "now I was looking at it again, through Daisy's eyes," indicates that the narrator is seeing the party and its extravagance from a different perspective, as if he is trying to view it as Daisy, his romantic interest, sees it. This shift in perspective evokes a sense of sadness or disappointment.

The last sentence, "it is invariably saddening to look through new eyes at things upon which you have expended your own powers of adjustment," means that it is always disheartening and unsettling to see familiar things through someone else's viewpoint, especially when you have adapted and become accustomed to them yourself. It implies a feeling of disillusionment or loss caused by the contrast between personal experience and a fresh perspective.

Overall, the quote represents the changing atmosphere of the parties, the narrator's growing detachment or familiarity, and the emotional impact of seeing something familiar through another person's eyes.
