MARY LOUISE KELLY, Host:

Commentator Ben Mattlin has a degenerative neurological condition. His spine is curved, and he uses a wheelchair that he controls with his mouth. On Halloween, when he was a kid, the wheelchair actually came in pretty handy - as we're about to hear. But as a grown-up, Mattlin says, his disability can make the holiday feel unsettling.

BEN MATTLIN: I never thought about a connection between disabilities and Halloween 'til I learned of the once-common fear of deformities - the limping, hunchbacked, hook-handed or one-eyed monsters of ancient fairy tales and old horror movies. Even the word creepy comes from the same word as the oldest term for folks like me, the politically incorrect "cripple."

As a kid, I tried not to think about what people might make of me, sitting in a wheelchair in my Batman or Lone Ranger costume. A hero who can't walk? Why not? Halloween is a celebration of the imagination, after all.

Sure, some kids teased. But I often scored more candy than my brother, who is not disabled. I saw no reason to complain about being treated differently. Yet as an adult, I began to feel uneasy about the creepy exhibitionism of Halloween, the way it encourages staring at all things weird.

I can't help wondering if Halloween doesn't promote ridiculing differences, even a kind of conformity. Yes, I know - for most people, Halloween is an escape from conformity. But for those of us who don't quite fit the norm, that's nothing special. In fact, demonstrating that you're not exactly what people expect is pretty much what disabled folks do every day.

When I take my own kids - who don't have disabilities - trick-or-treating, I often attract as much attention as they do. It's not the same in daylight. When kids see me on the street, careering in my power wheelchair, they often say things like, wow, can I have one of those? Hey, my chair is an amazing, transformative device.

Cool, isn't it? I'll say back. I figure I should do my part to make kids comfortable with people like me. Sometimes, I have to tell the adult with them that it's okay, that kids shouldn't be forced to look away. I encourage them to ask questions, to learn.

Maybe I should see Halloween as an opportunity for grown-ups to do that, too. The holiday challenges us to stretch our perceptions, Maybe it can also teach us not to shrink away from the unfamiliar, or judge appearances. This Halloween, I'll try to remember that I really have nothing to fear.

LOUISE KELLY: Commentator Ben Mattlin will spend his Halloween in Los Angeles.
