This series really started when I was 16. A friend of mine and I used to go to a coffee shop in Manhattan. The tables were arranged so that all we could see out the window was people's feet. Many times we would sit there trying to decide what the rest of the person looked like. As a joke, we wrote an article about this mystery. Much to our surprise we sold it to a magazine for $25! I think this series and the Stalled series grew out of that experience.
