I don't have any trouble looking people in the eye, but I have been told by many people that my voice is very monotone and devoid of expression, especially when I'm explaining how to do something.
I can hear very high-pitched noises, too (although they don't bother me.) I can walk into any normal sized house and immediately be able to tell if there's a TV on, even if it's muted, somewhere because of the noise that they spew off.
