Fitzgerald gives great attention to the details of contemporary society: Gatsby's party is both a description and parody of Jazz Age decadence. It exemplifies the spirit of conspicuous consumption, and is a queer mix of the lewd and the respectable. Though catered to by butlers and serenaded by professionally trained singers, the guests are drunk, crude, and boisterous. The orchestra plays a work by Tostoff called The Jazz History of the World; though it had had a fantastic reception at Carnegie Hall, the piece is the antithesis of classical respectability.
After the birth of their child, the Fitzgeralds moved to Great Neck, New York , on Long Island , in October 1922. The town was used as the scene of The Great Gatsby .  Fitzgerald's neighbors in Great Neck included such prominent and newly wealthy New Yorkers as writer Ring Lardner , actor Lew Fields , and comedian Ed Wynn .  These figures were all considered to be " new money ", unlike those who came from Manhasset Neck or Cow Neck Peninsula , places which were home to many of New York's wealthiest established families, and which sat across the bay from Great Neck. This real-life juxtaposition gave Fitzgerald his idea for "West Egg" and "East Egg". In this novel, Great Neck (King's Point) became the "new money" peninsula of West Egg and Port Washington (Sands Point) the old-money East Egg.  Several mansions in the area served as inspiration for Gatsby's home, such as Oheka Castle  and Beacon Towers , since demolished. 
Nick reconsiders his decision to live in the East and prepares to return to his roots:
“I see now that this has been a story of the West, after all-Tom and Gatsby, Daisy and Jordan and I, were all Westerners, and perhaps we possessed some deficiency in common which made us subtly unadaptable to Eastern life.”
People seek Nick out because of his non-judgmental nature, oftentimes to his dismay:
“...I’m inclined to reserve all judgments, a habit that has opened up many curious natures to me and also made me the victim of not a few veteran bores. The abnormal mind is quick to detect and attach itself to this quality when it appears in a normal person, and so it came about that in college I was unjustly accuses of being a politician, because I was so privy to the secret griefs of wild, unknown men. Most of the confidences were unsought-frequently I have feigned sleep, preoccupation, or a hostile levity when I realized by some unmistakable sign that an intimate revelation was quivering on the horizon…”
