I could feel myself changing physically. It was like something dropped out of the sky. Seeing her on the fire escape had given me a certain feeling, and then when I saw the photograph of her, it gave me a similar feeling. And I thought that was an incredibly powerful thing - that a photograph could give you a feeling that was similar to a feeling you had in the physical world. Nobody could've told me that. I knew what I was going to do for the rest of my life.
