Lyric discussion by nanobody 

People keep saying this song is about a love that ended. I think it's about one that never started. He liked her; she didn't; he moved on; they randomly see each other; she sees what she missed before, but too late--he's no longer interested. He leaves to do whatever delightful thing he has planned (or that she jealously assumes he has planned) and she's left to ponder what could have been.

I don't think she's censoring herself with the "bolt like a horse" line. I think she deliberately chose it for its ambiguity, its duplicity of meaning. And both meanings work very well within the context of the song.
