The Girl In Red

This is one of those shots I could look at and wonder about forever. I don't know why I like it so much. There she is, standing there, a well-groomed island of color, isolated from the drab, colorless, sloppy people sitting on the curb. Why is she there? Why is she alone? What's going through her mind? What are they all waiting for? Thanks to Verbose Coma for the image.
