I've been following this thread with interest, not because any of my family has been diagnosed with Asperger's, but because I think a lot of us fall somewhere on the spectrum, and also because it's important for all of us to learn as much as we can about what makes others behave the way they do.
I few years back, my parents were sorting through old papers, and came across my early report cards, which they gave to me. I was somewhat taken aback by the comments from some of my early teachers, voicing their concerns for me, my "shyness", and how I had a hard time socializing with my peers. I was the child with my nose stuck in a book. During summer vacations, I'd go to the library multiple times a week, because we could only take out three books at a time, and I was finished with those in a day or two. Bear in mind, this was in the late 1960s or early 1970s, when children weren't "evaluated", other than academically. As I grew older, I never did form the social bonds that my peers did - I was usually the friend-of-a-friend, who got invited to things because it would have been rude to exclude me. I always had one or two closer friends, usually roommates, but . . .
As an adult, most of my social connections are through work - I have a couple of coworkers that I hang out with during the day, and occasionally see outside, but not often. I'm married to my best friend, and we have three great children. I have a good life, but I know I don't have the social circles that a lot of other people have. And I don't really miss that. That's not to say that I don't care about the people around me - I just have an easier time relating from a distance. It's so much more comfortable for me to share my thoughts and wishes from the other side of this keyboard than in person.
Going back to what justbugged said about not being "allowed" to express some of her thoughts: I don't know how old you are, but I think it's a bit like being lefthanded - my husband went to a Catholic elementary school, where he had his lefthandedness beaten out of him. "Different" wasn't tolerated. At least now, people (including parents and educators) understand that we're not all wired the same, and some of us need a different approach in order to succeed in life.
