Once the children have all gone off to college and gotten married, their parents realize that they have more time to themselves now that their children have accomplished their dreams, but their house and lives feel a lot emptier nonetheless.
The music video was directed by Deaton Flanigen and premiered in early 2003.
In 2005, the song was released by Susie Luchsinger on her album Count It All Joy, with more instrumental aid.
