I agree that some people seem to mysteriously click with others just fine whereas some people struggle. Social chameleons, perhaps. I personally do some mimicking, socially speaking, and sometimes without realising, to "fit in"; it's not as fake as it sounds, but it can often help. If I don't mimic, I take something from what I see of them, and relate to it; I'll find some common-ground and build on it. I don't know you, for example, but we have some understanding with your post, thus in a social setting, this has helped us just a little bit. xD Weird example, but you know what I mean, hopefully.
