"I would never sit and write a song in front of anyone, because you're so vulnerable. I don't know at what point in the process that it becomes acceptable to pass them on. When a song wants to be written, it will be written. When it does come, I will very rarely go back and edit lyrics. I'm quite a rational human being, and the only part of my life that I can't rationalise, or can't make sense of, is how a song gets written or why."
