It's the loneliest feeling in the world-to find yourself standing up when everybody else is sitting down. To have everybody look at you and say, 'What's the matter with him?' I know. I know what it feels like. Walking down an empty street, listening to the sound of your own footsteps. Shutters closed, blinds drawn, doors locked against you. And you aren't sure whether you're walking toward something, or if you're just walking away.
