This summer I met a girl who could
sing beautifully, but who was a smoker. Over the course of a month I
got to know her better and better, until after I'd
known her for about two weeks I couldn't take it anymore...
I went up to her and said, "You know... smoking will kill your singing voice."
And she looked straight back at me and, with her voice solemn and a tear in her eye, said "I know."
That is addiction.
