You put together two people who have not been put together before; and sometimes the world is changed, sometimes not. They may crash and burn, or burn and crash. But sometimes, something new is made, and then the world is changed. Together, in that first exaltation, that first roaring sense of uplift, they are greater than their two separate selves. Together, they see further, and they see more clearly.
