"Why Nathaniel?  As in why did I fall in love with him?"  I nodded.  "Oh, I don't know.  Why does anyone fall in love with anyone?  I don't believe we each have some single special person waiting for us out there, if that's what you're getting at.  I've been in love too many times over the years to buy into that old canard.  It's more a question of timing, you know?  As if we all have these elaborate locks inside our hearts that are constantly changing shape, and every once in a while, someone happens along with the perfect key.  Love is nothing more than a fortuitous collision of circumstances.  And then you discover you've ended up spending fifty years with someone."
