Were you expecting the book to end with some sort of confirmation that Josh and Emma wind up married in the future? We admit that we kind of were. But no such confirmation ever comes—heck, the camera even cuts away before Emma and Josh actually kiss. Check out the last sentence:
I feel her breath on my lips as we both whisper, "Hopefully everything." (65.42)
So what gives? Well, a big part of the point of this book is that the present matters more than what's to come. After fretting over where they'll be in fifteen years for most of the book, Emma and Josh have finally let the future go in favor of hanging out in the here and now. And not really knowing what happens with their relationship forces us as readers to do the same thing. Maybe they'll make it, maybe they won't, but right now, they're both definitely pretty happy—and this matters more than what awaits them down the road.
