Being a proud nerd, I'm not ashamed to declare my love for science fiction & fantasy novels, so I couldn't have been happier when the best man's speech at Emily & Zak's wedding involved parallel universes. He pointed out that every decision we make means another decision we forego, one of the biggest being marriage. Emily & Zak decided to bind their lives together at the Chapel Dulcinea on a day that should have rained, but didn't, and then partied the night away with friends and family at the Palm Door amid twinkling lights. That decision to become husband and wife sets them down a path together for the rest of their lives and eliminates a million other paths. But as Kellan pointed out, the fear of not know what you're missing pales in comparison to the joy of choosing a path with the one you love.
