I prefer the term Asperger's, but since it is no longer a diagnostic category, I will say Asperger's/ HFA. Unfortunately most people don't get high functioning autism, so I generally just do what I need to do to blend in to the "normals'" world. If I don't need to explain why I am the way I am, that just makes things easier for me to navigate- until I need to drop off the planet for a day or two here and there to preserve my sanity, that is.
When I tried to explain the fact that I'm Asperger's/ HFA to my mother all she could say is, "I know you're not ret*d. You have to be ret*d to be autistic." One of the many things my parents did with me when I was a child- because they knew I wasn't "normal," but didn't know how or why I was so different- was to have me evaluated by every psychologist or educator they could convince to do it. At age 6 I was tested as having an IQ of 157 and considered to have reading ability comparable to a college freshman. But I had no idea how to interact with my peers, and (unknowingly) intimidated many adults. I didn't know I was HFA until I was 35 years old, although my parents and various teachers, psychologists, etc. identified and tried to work with some of the pieces of HFA, such as social ineptitude, gross motor deficits, and anxiety and depression.
After I was diagnosed and began to learn more about ASDs myself, I told Mom that she needed to get some fresh information on autism and hyperlexia. Now I think she gets it that people on the spectrum can have below average, average or even above average IQ's. Many NTs will make the mistake of thinking that just because a person who is HFA has a high IQ or who can "act normal" that somehow that makes them "normal." Believe me, it doesn't. A high IQ just gives one the capacity to get in more trouble. It makes you less "normal," although you can use your intellect to compensate for the things you know are not really connected, and you can compensate for the skills you don't have. Age and time and experience are great allies in this experience. I'm a lot more comfortable in my own skin at age 45 than I was 10 years ago or 20 years ago.
I'm hyperlexic, so I have a different experience with language than most. I am adept with written language, but not so much with conversational skills. I'd much rather text than talk.
I like to think of my wiring as an alternative road map. I can usually get to the same places as NTs but I have to take different paths. I can take the freeway to a lot of places most people can only get to through the back roads- but I have to take the back roads to a lot of places that others can access from the freeway. Over the years I've learned to make it work.
