I fittingly overheard this at a sheepskin boots booth at the Boulder Fine Arts Festival:
"And every time she goes back there she gets an overwhelming sense of regret, because everything she remembers has changed."
Odd, to feel regret on behalf of something else (in this case, presumably a city or a town). I always thought of regret as being defined by something you wish you had done differently. Not something that, out of your hands, turned out differently by itself. I am assuming here, of course, that the woman in question didn't leave her hometown in flames, set off by her lighting fire to the city hall after freeing all the prisoners from the jailhouse and inciting revolutionary thoughts in all the townsfolk.
