How is Nick's attendance at Gatsby's party different from the other party goers?

Answer: Nick is the only one who is invited to a party.

Explanation:

In Great Gatsby, a novel written by F. Scott Fitzgerald, Nick is the narrator of the story and Gatsby's neighbor.

Gatsby lives in a luxurious mansion and throws parties, hoping that he will impress the love of his life, Daisy.

At his parties, guests drink and dance all night by his swimming pool, while a live orchestra plays.

The guests usually just show up at the party - everyone is welcome. However, Nick is the only guest who actually receives an invitation. Gatsby sends his chauffeur to Nick's house to invite him to a party.
