Spot the Fake Smile

Thanks for the responses for my previous post, guys! I just wanted to know what everyone's approach/thinking was on what determines love for you, so it was nice to read what people thought.

This test is pretty fun: http://www.bbc.co.uk/science/humanbody/mind/surveys/smiles/index.shtml - how good are you at spotting fake smiles? I got 17 out of 20. What about you? :)

On the Moment

It is wrong to think that love comes from long companionship and persevering courtship. Love is the offspring of spiritual affinity and unless that affinity is created in a moment, it will not be created for years or even generations.
~ Khalil Gibran (via Jason Mraz)

I'm extending the trend...discuss! Is it necessary to have that "moment" or not? If it is, how long should you wait to experience that "moment" to happen until you decide to move on?

Do you think marriage can work between atheists and theists? What about between democrats and republicans? I guess individuals can make it work, but what about for their families?
thoughts please
