I used to think--and given the way we ended up, maybe I still do--that all relationships need the kind of violent shove that a crush brings, just to get you started and to push you over the humps. And then, when the energy from that shove has gone and you come to something approaching a halt, you have to look around and see what you've got. It could be something completely different, it could be something roughly the same, but gentler and calmer, or it could be nothing at all.
