The Great Gatsby Symbolism

During the novel, The Great Gatsby by F.Scott Fitzgerald symbolism is a mayor topic for discussion. As the story progresses, we can see how the characters are affected by certain things and how some of them shape them to certain extend. Some symbols are obvious, such as the green light Gatsby observes, or the yellow car he drives; others aren't so visible, such as the fact that Gatsby maintains distance with alcohol. He has lots of parties, and is a great host, however, he doesn't drink that much, it is strange, for someone who constantly lives in the social network. Another symbol that comes to my interest, is the pool. Gatsby never uses the pool, it is full during summer, but it is never used. Ironically, the only time he uses it, he gets murdered.
