I'm thinking about how, when I am with a group of people who don't know each other, and all of a sudden I notice that some people have made connections. And I have no idea how or when it happened, and it didn't happen with me. There is some sort of body-language-reading and/or empathy going on there that I am bad at, either because it's a talent I lack or because I don't have a lot of experience with those situations. It's frustrating.
I wonder how often other people feel that way. I wonder how often self-identified "socially normal" people feel that way.
