It occurred to me one day that authors often build metaphors into a story and that it seems like maybe God puts metaphors in our lives too. The more that I thought about it, the more I realized that it was true! The first half of the songs is based on real things I observed - yes, that big dumb dog really did try to hump me! But the second half is just something I made up. The main thing that I wanted to get into the song were the references to the Tennessee Williams plays ("The Glass Menagerie" and the "A Streetcar Named Desire").
