I would never talk just to be social. Now, to sit down with a bunch of engineers and talk about the latest concrete forming systems, that's really interesting. Talking with animal behaviorists or with someone who likes to sail, that's interesting. Information is interesting to me. But talking for the sake of talking, I find that quite boring.
Normal people have an incredible lack of empathy. They have good emotional empathy, but they don't have much empathy for the autistic kid who is screaming at the baseball game because he can't stand the sensory overload. Or the autistic kid having a meltdown in the school cafeteria because there's too much stimulation.
