I find other aspies much easier to talk to than NT's. In fact with other aspies I can be quite social - maybe because they have something real to say instead of just meaningless small talk?
With NT's, when yet another person asks "How are you?" or "Did you have a good weekend" (questions I have already answered several times this morning, though probably incorrectly - i.e. "I've had a cold all weekend!") I just switch off.
