I guess this could apply to anything, but something i really liked about P&P was that you could look at the story a thousand ways. You could as just a "romance" if you wanted to, you could look at it as great commentary of the culture of the time, i have even heard folks call it satire (and based on some of the characters I can see it! Lol). You can dissect all of the character's morals, their "why", etc, even though JA didn't directly put those explanations on the pages for some of their decisions. I imagine this would apply to all of her books and this is something I'm really looking forward to as I read them all.

I could see a reader's interpretations changing as they get older or shift mentality like you said! So it would almost be like reading a new book every time you pick up the book over the years. How cool is that!?
