Spectrum Connections Meetup group for social outings among teens and young adults. We haven’t tried it but we’ll see if #1 or #2 are interested.
#1 would be very interested if girls were involved. Unfortunately autism disorders have an official gender ration of 4:1 or 5:1. In the disability setting the ratio feels more like 8:1.
For #1 this ratio might be the worst thing about his cognitive disabilities. Along with not being able to go to university of course.
