And it isn't as if I am useless. I once spotted a factory door ajar at a time it was always closed and locked, and found a policeman, who took all the credit for the burglary that he interrupted. But the police did give me a certificate when I got the license plate of a hit-and-run driver who knocked a bicyclist senseless one spring afternoon. And in something awkwardly close to the takes-one-to-know-one category, as I cruised past a park where children were playing one fall weekend, I spotted a man and I knew as soon as I saw him, hanging by the entranceway, that something was completely wrong. Once my voices would have noticed him, and they would have shouted out a warning, but this time I took it upon myself to mention him to the young preschool teacher I knew who was reading a woman's magazine on the bench ten yards from the sandbox and swing set and not quite paying enough attention to her charges. It turned out the man was recently released and had been registered just that morning as a sex offender.

This time, I didn't get a certificate, but the teacher had the children paint me a colorful picture of themselves at play, and they wrote a thank-you across it in that wondrously crazy script that children have before we burden them with reason and opinions. I carried the picture back to my little apartment and placed it on the wall above my bed, where it is now. I have a musty brown life, and it reminds me of the colors I might have experienced if I hadn't stumbled onto the path that had brought me here.

That, then, more or less, is the sum of my existence, as it is now. A man on the fringe of the sane world.
