"When you love someone, you open yourself up to suffering. That's the sad truth. Maybe they'll break your heart. Maybe you'll break their heart. But you'll never be able to look at yourself the same way. Those are the risks. You see two people and you think...they should be together. But nothing happens. And that's the burden. Like wings, love has a weight. We feel that weight on our backs, but they are a burden that lifts us. Burdens which allow us to fly"
-- Bones, TV show, narrated by the character 'Jack Hodgins'
