I've learned enough not to bring it up with either of them. My guess is that they don't have a clue. But then neither did I. I actually stumbled onto my own autism quite by accident. Though it did involve some serious self-denial at first.
Caught a show on the Natl Geo channel years ago about people with some strange obsessions. Learned about this thing called Aspergers Syndrome though I wasn't even looking for it at the time.
