Cover art for Daughters lyrics by John Mayer Trio

This song is about twin baby girls, and how one of them is fine and the other meet this terrible man who treat it so unfairly, and it's hard for the next man to clean up cause she can't get clean in her mind or body. The other baby girl is not mentioned in this song she's fine. but the man here is willing/able do it because true soldiers defeat any obstacle, he expresses he's not thrilled of this clean up task rather I feel he feels it's his duty. And then the resolve is God bless America!
