Like everyone else in the known universe, I read this first in High School. At the time, my impression of it was that it was a bunch of fashionable, old, rich alcoholics leading completely incomprehensible lives. Reading it again 15 years later, now that I'm older than Nick (the narrator) and probably older than Gatsby himself, wasn't a lot different. The only change is that now the characters seem like a bunch of young rich superficial people living foreign and incomprehensible lives. I enjoyed the story but it's short and overrated and I can think of about 100 books that'd be better at getting high school kids interested in literature (how about the The Count of Montecristo for a mysterious rich guy?).
