Taken from Flyleaf's biography:
Lacey: The bridge says, "Down here love wasn't meant to be for me, all is vanity underneath the sun." The phrase makes you ask, "What would the world be like if we took love out of it?" Love is painful. It requires work. It's selfless. Even though it's difficult, if you take that out of the earth you're going to end up with nothing. C.S. Lewis said, "The only place in all of the world where you can escape the dangers of love is hell."
