It never ceases to amaze me the crud that teachers will subject their students to. This was my case in high school. I was forced to write numerous papers talking about how awesome this book was.
In reality Ernest Hemingway was a total Eeyore. Everything he writes is depressing and boring. It's crazy that every one applauds him as being such a realist. I feel sorry for anyone who sees life in that way.
I guess it's fine if you read a little Hemingway to broaden your horizons. Just be sure to read positive stuff too.
