Passion

Well, you're sort of a doctor, but this is hard to say. Well, Bingo wouldn't sleep with me very much, if you know what I mean and if you'll pardon the expression things was pretty much going to hell. So one night I just up and told her why I got married and what she got married for and from then on things was different I can tell you and we got to love one another all over again and it was like a different world and we used to laugh at her old women.
