Extremely Loud and Incredibly Close

I finished this book a few weeks ago and my roommate is almost done reading it. We enjoy discussing the thought process of Oskar and why these people are acting they way they are. It's a mini book club of sorts between ourselves. 

"Well, what I don't get is why do we exist? I don't mean how, but why.' I watched the fireflies of his thoughts orbit his head. He said, 'we exist because we exist. . .we could imagine all sorts of universes like this one, but this is the one that happened." 

-Johnathan Safran Foer

Mainly we enjoy how the book actually makes us feel.
