It made me wonder if it is easier to leave a person or a city - though of course so many times the two are interconnected and you can't be sure what you're turning your back on.
Or maybe you do find out, but it's not until you're really out there, on the road. Then, if it feels like the road is stretching toward something, you find out you've still got horizons. But ifall you can see, in all that space, is a person, that person's no mirage. He won't recede. You just have to turn around and find him again.
