“You put together two people who have not been put together before. Sometimes it is like that first attempt to harness a hydrogen balloon to a fire balloon: do you prefer crash and burn, or burn and crash? But sometimes it works, and something new is made, and the world is changed. Then, at some point, sooner or later, for this reason or that, one of them is taken away. And what is taken away is greater than the sum of what was there. This may not be mathematically possible; but it is emotionally possible.”

Julian Barnes
