Most of what we think of as socialization (ie small talk, certain scripts like "How are you?" "Good.") is just a show. NTs don't actually care about what they're saying--95% of what they're actually saying is unspoken, and entirely different from the words. It's partly acknowledgment that they want, and partly a sort of social "check" that you have to pass without setting off any flags. Sometimes they want to make certain shallow pretensions, such as superficial "caring" or presenting themselves as "cool". It's all ritualistic, sometimes feeling each other out, sometimes just posturing. As a general rule, people talk a lot but say very little... at least with their words.
I also suspect that we on the spectrum don't usually mask as well as we think we do. There's simply too much invisible and unspoken stuff that we have to attempt to learn, study, and replicate without getting flagged. My solution has been to study psychology and study humans and their interactions, and try to figure out what drives everything. My socializing is partly masking in the traditional sense, and partly "translating" myself into NT--that is, figuring out how to present so that they can hopefully understand me. Since I have to translate their communications as well, mis-translation can happen on either end. But, it is more likely to pass the checks, because I'm being more authentic, and they flag insincerity very easily. (Which is pretty ironic given that most of their words are fake.)
