No, her head is too hard! No offense, Granny.
You guys do not understand autism. These people do not perceive the world the same way "we" do. You can't just say he "should" do this or that. Or he could if he tried harder or if he really wanted to. He truly can't, just like you or I can't fly like a bird. His reality is different from ours. He may want to drive, or help, or hold down a job. But he ... it's like ... he lives in a different dimension that only occasionally melds into ours. That's why he gets lost even when he's close to home. He can only perceive what's right around him, right now, and it doesn't ralate to the rest of the world. At all.
I don't know if I'm explaining this well at all. My DH is mildly autistic. And so is my Kid. The DH more so than the Kid, actually. So I have a little insight into it.
