“Show me a hero, and I’ll write you a tragedy,” said FSF. To me the difference between Fitzgerald and Hemingway was that the former had a better understanding of tragedy. Maybe he understood it too well.
I have seen a few of Englishman Noel Coward’s plays but not read his work or studied it. It seemed to me he dealt with themes similar to Fitzgerald’s but had more of a sense of humor about it. This is something I heard when living/working overseas: that Americans are too serious.
We have reasons to be serious.
