Not AS/HFA, but I feel like it's on topic: one of my friends has a little sister who just turned 13 with PDD-NOS. She's got some brain damage, so she displays many symptoms of LFA, but not enough to be diagnosed. She's sort of a smorgasbord of different disorders, and she's definitely one of the nicest people I've met
(My friend tells me that apparently there's a romance budding between her and a boy at her school with Down Syndrome. They're super cute about it and he holds the door open for her and everything. Adorable.)
Also, in 3rd grade my class had a sort of "fair" for the kids in the special needs program. They all had their own booth where they'd show off some talent, etc. There was a LFA boy about my age who was an unbelievable artist. He could barely speak, but he could draw better than most adult artists I've met. He was taking requests so I asked him to draw grapes, and in under a minute he drew a bundle of life-like grapes with crayons.
This is way before I had heard of AS, let alone suspected I had it (though every teacher I ever had told my mom they thought I was autistic, which she laughed off), and I remember thinking, "Wow, I wish I had autism so I could draw that good."
