Answer:
At Gatsby's lavish parties, the general mood is one of carefree but false happiness.
Step-by-step explanation:
The novel "The Great Gatsby" by author F. Scott Fitzgerald has as one of its themes how decadent society has become and how miserable the upper class really is. The grand parties thrown by the protagonist, Jay Gatsby, are a representative of that. The attendees are superficial people. Their lives have no meaning, no greater purpose. They all have secrets, affairs, crimes to hide and, yet, they are all looking around themselves, searching for someone else to judge and condemn. Their roaring happiness is fickle and fragile, watered by alcohol and music until it dries out after the party is over.
