This Mess We're In Lyrics

Lyric discussion by Arianrhod

The discussion taking place on the PJ Harvey thread for this song suggests that the song might be about a pair of lovers who ae obligated to someone else, perhaps a spouse (thanks to Mystic_Muzic), and whom get together for one night, decide it won't work, and then call it quits for good in a terribly tragic love story.

Yeah, that's the sense I get from this song.
