Breaking down everything and analyzing everything where you are "inside your own head" or trying to change your way of interacting is too complicated a way of looking at the situation. Why even look that deeply into it? Most people are sheep and are shallow and boring and soul-less and have no original thoughts. Whether they trained themselves to be that way to be accepted or if they just genuinely are that way, who knows. If you want to connect with people, most people or 99.9% in my opinion are not even worth knowing to begin with.
It is true that in a more relaxed environment, people will finally open up a little and not be robots, but I mostly doubt that. I think in a more relaxed environment, eventually, people will open up with still extremely guarded opinions. I had a friend for 7 years or drinking buddy and learned absolutely nothing revealing in the entire 7 years and we went to about 500 pro sports games together and bars in penn station and talking on the phone about an hour a day. Ironically, he was in a fraternity at one point 20 years before i knew him, in college and had a million friends with absolutely nothing revealed about himself or his demons or anything close to personal.
People will either open up to you and reveal who they are, or they won't. You can't be like kinda pregnant is the analogy i will use. I don't need to have deep philosophical conversations with people, but most people want to talk about the weather and the same safe topics over and over and over. Of the women i dated and friends i had which i have now been alone 8 years, almost no one is genuine about even the slightest personal opinions. If they even open up about themselves using humor that would at least be something. People are so guarded it is ridiculous. If you want to give people credit by pretending that they were somewhat revealing, to sleep better at night, whatever you want to do.
My real point is that trying to morph into a social being or being confused why you can't interact the right way is pointless, because most people are not worth interacting with anyway to begin with, or will bore you to tears, or a combination
