I'll take a guess at this.
As an adult aspie, who is much too old to have been diagnosed as a youngster, all I could do was to find my way in life as best I could. And I did well enough, as have the few other adult aspies who I've met face to face. But we are kind of a lost generation. Many of us learned to pass for "normal," most are still not officially diagnosed, and there doesn't seem to be a lot of willingness to accept that we even exist, it's as if there were no autism before 1975. Look for an academic paper on aspies over 30 some time. ANYthing about aspies over 30, any mention at all. You will find nothing.
So my thought is that there are probably a lot of parents who wonder what to expect that their kid's life will be like. They want the long term prognosis, and there's no information available. I bet they'd love to get acquainted with some adult aspies, and probably pick their brains a bit while they're at it.
I'd favor having a little privacy, myself, but maybe you could have a parents night from time to time.
