Welcome! I'm also here primarily for my son, who is somewhere on the spectrum (although he is just 3 so we're not sure where exactly - we're thinking Aspie with speech delay but there is a long wait for the local specialist). I have been diagnosed as ADHD (inattentive) and find that I share a lot of traits with my son as well as the Aspies at WP (extreme introversion, difficulty following group conversation, cold/aloof seeming, no volume control, high IQ, hyperfocus, special interests, left-brain tendencies, incompetence at deception, and I freak out in a big way if I'm late or if strangers invade my personal space; I also pick at the skin on my scalp, which is apparently supposed to be a stim). I'm reluctant to identify as an Aspie as some of my other traits (changes in routine don't bother me overmuch, and I love trying new things) seem pretty incompatible with AS as far as I can tell. And I'm friendly enough, just don't have the energy or desire to maintain a normal-size social circle. Various online assessments put me either near or just barely on the spectrum. Sheesh, I'm verbose. Moving on.
At any rate, I suspect having a number of Aspie traits, regardless of a diagnosis, will give you insight as to how to help your son navigate the NT world. Imagine how difficult having a child on the spectrum would be for extroverted parents who don't have any odd little quirks! Sure, they "model appropriate social skills," but at the same time they probably don't understand the need to have six hours of alone time to recuperate from "being sociable." Whereas you or I might be fine with that, because that would give us OUR alone time.
See you around, I hope! I feel weird interjecting in most threads since most of my Aspie-like traits are probably just ADHD, but I do post on the forum for parents of AS children.
