"How come love sounds so violent? You fall head over heels. You're struck by Cupid's arrow. You take the risk of having your heart broken. From an outside perspective, it sounds impossibly painful, not worth the trouble. And yet we do it every day. We keep coming back for more. Why? If it weren't so perilous, maybe we wouldn't crave it so much. Maybe it has to be brutal, in order to work. People come in so many shapes and sizes that it takes a bit of force in order to fit together perfectly. But you know what they say about a break that heals: it's always stronger than before."
