I think both my parents have AS-ish traits.
My father is very much a loner (although married with kids), he is a "nature boy" and needs a lot of time alone in nature. He also has a terrible temper; he gets easily frustrated and is quick to rage, although it blows over quickly too. Unfortunately apart from those two things I don't know much about him, except that he should NOT have had kids.
My mother is very proper in regards to speech, grammar and manners, obsessively clean and tidy, highly sensitive to eating noises, not particularly affectionate, and can be kind of stand-offish sometimes... she is also very scatterbrained, which is getting worse as she gets older.
Interestingly, my husband's parents both show some HFA/AS traits as well, but my husband himself has almost none. He's not exactly your average NT but he is far from aspie. Luck of the genes, I guess.
