Nevertheless, Gatsby is generous to the point that people arrive without invitations and show up merely to use his house, cars, or boats.
However, it seems that Gatsby sets Nick apart for some yet unknown reason because he is sent a hand written invitation.
At this point in the novel, Gatsby is still a very mysterious figure that is surrounded by rumors and lies, much like the Gatsby's real life.
Nick describes Gatsby's parties as being grand, elaborate affairs emphasizing that he is the perfect host, both courteous and generous.
So he invented just the sort of Jay Gatsby that a seventeen year old boy would be likely to invent, and to this conception he was faithful to the end.” (Fitzgerald 98).
Gatsby’s past scarred him, which left him wanting change but unwilling to expose himself to do so.
He had never succumbed to the temptation to go over to one of Gatsby's parties, showing Nick's integrity.
When Nick arrives at the party he goes from being a spectator to a participant in the chaos.
Nick soon discovers that the glamorous, refined partygoers are in fact quite shallow and not very interesting.
Soon, Nick stumbles upon Jordan Baker who he spends his time with for the rest of the evening and they begin to mingle with other guests at the party.
