The strong attention focus that is typical of AS is responsible for much of the anger/rejection I get from people. I'm focused on one thing, but expected to be able to focus on several at the same time, which doesn't happen naturally for me. I can do my best if I know beforehand that I have to pay attention to several things at the same time, and even then it's hard to accomplish.
A typical example from my life: at the hospital where my mother is staying, there's a rule that if the nurse comes in you have to leave the room to let them do their work. I was talking to this patient in their bed, to give them some attention, so I didn't notice the nurse standing next to me. She got angry I hadn't gone out or even acknowledged her presence by moving aside.
Also, I get so much of the "you're not listening to me!" because I don't make eye contact.
I find that the hardest part of having a high-functioning autistic disorder is that so many of the traits/symptoms/behaviors are invariably interpreted selfishness, and there's no way in hell you can make them understand that it's NOT out of selfishness.
