Sociopath” and “psycho” were two of the most common field diagnoses for my look and expression. I heard it all the time: “I’ve read about people like you. They have no expression because they have no feeling. Some of the worst murderers in history were sociopaths.

They enrolled me in a group for troubled kids. We would meet each week in an old farmhouse owned by the university and talk about our problems getting along. . . . . They didn't teach me to get along, but I did learn that there were plenty of other kids who couldn't get along any better than me. That in itself was encouraging. I realized that I was not the bottom of the barrel. Or if I was, the bottom was roomy because there were a lot of us down there.

Unlike some older brothers, I never set him on fire, or cut off an arm or a leg, or drowned him in the tub.

Appearing as a character in my brother’s books taught me something about myself. For most of my life, my history as an abused child with what I saw as a personality defect was shameful and embarrassing. Being a failure and a high school dropout was humiliating, no matter how well I subsequently did. I lied about my age, my education, and my upbringing for years because the truth was just too horrible to reveal. His book, and people’s remarkable acceptance of us as we are, changed all that. I was finally free.

There are plenty of people in the world whose lives are governed by rote and routine. Such people will never be happy dealing with me, because I don’t conform. Luckily, the world is also full of people who care about results, and those people are usually very happy with me, because my Asperger’s compels me to be the ultimate expert in whatever field of interest I choose. And with substantial knowledge, I can obtain good results.

When Martha first met me, I was anxious and jumpy. I was always tapping my foot, rocking, or exhibiting some other behavioral aberration. Of course, now we know that’s just normal Aspergian behavior, but back then other people thought it was weird, so of course I did, too. One day, for some reason, she decided to try petting my arm, and I immediately stopped rocking and fidgeting. The result was so dramatic, she never stopped. It didn’t take long for me to realize the calming effect, too. I like being petted and scratched. “Can you pet me?” I say when I sit next to her.
