So from now on I'll just steal cartoonist John Atkinson's witty summaries and sound really really smart at parties. The key, I believe, is to wait for someone else to mention the book and then write it off with a biting summary.
Other person: "I just started reading The Odyssey, it is captivating. I am brilliant for reading and enjoying it."
Me: "Oh, that's just about war vet who takes forever to get home and then kills everyone. PTSD, much?"
(See how I added the PTSD thing, so that it has the flavour of my own personal interpretation?)
