Characterization : Nick
Direct characterization:Nick is a young man from Minnesota after being educated at Yale and fighting in World War I goes to New York City to learn the bond business. Honest, tolerant, and inclined to reserve judgment, Nick often serves as a confidant for those with troubling secrets. After moving to West Egg, Nick quickly befriends his next-door neighbor, Jay Gatsby. As Daisy Buchanan’s cousin, he facilitates the rekindling of the romance between her and Gatsby
Indirect characterization: Every one suspects himself of at least one of the cardinal virtues, and this is mine ,I am one of the few honest people that I have ever known
Direct characterization:Gatsby is a wealthy young man living in a Gothic mansion in West Egg. He is famous for the lavish parties , but no one knows where he comes from, what he does or how he made his fortune.Nick learns that Gatsby was born James Gatz on a farm in North Dakota; working for a millionaire made him dedicate his life to the achievement of wealth. When he met Daisy while training to be an officer in Louisville, he fell in love with her. Nick also learns that Gatsby made his fortune through criminal activity, as he was willing to do anything to gain the social position he thought necessary to win Daisy. Nick views Gatsby as a deeply flawed man, dishonest and vulgar, whose extraordinary optimism and power to transform his dreams into reality make him “great” nonetheless.
Indirect characterization: "I thought you inherited your money." "I did, old sport," he said automatically, "but I lost most of it in the big panic – the panic of the war." I think he hardly knew what he was saying, for when I asked him what business he was in he answered, "That's my affair," before he realized that it wasn't the appropriate reply. "Oh, I've been in several things," he corrected himself. "I was in the drug business and then I was in the oil business. But I'm not in either one now." This shows he tells fibs .
The Great Gatsby library is the symbol because it shows how it seemed how things came alive.
