I read it a long time ago and like you have very little recollection of it. However in high school we also read Homer and several plays by Shakespeare and remember a lot of details - I think my English teachers did a great job of explaining the context and chairing our discussions about those other works. I was thinking it’s hard to relate to Tom and Daisy in high school but then the other works are separated from us by culture and centuries (though to be fair translations we read for Homer are each a work in themselves)
