There are a lot of jokes about extroverts adopting introverts and so forth, but the answer on really how to get to know one is less obvious to the world. It is clear as a bright sunshine day to introverts.

I know I have little patience for small talk. I don’t want to hear about surface level nonsense that is mostly irrelevant. It becomes a Facebook discussion on saying anything you can to get the most likes in the conversation.
That is a social rule that was written by extroverts because they are louder and dominate the discussions. When the yapping starts, I watch the introverts shutting down. It is mentally draining. It takes me days to recover from having to listen to this.
I’d rather just not talk and I don’t go to a lot of things just to not to have to hear it. I like the people, but the energy draining isn’t worth it.
On the other hand, if you want to talk about something meaningful, watch me open up. We don’t have to talk about derivative equations, but cut the shit and meaningless banter. I have a great depth of knowledge on many subjects and enjoy the conversation that is intellectually stimulating.
Fortunately, I am not bound by whether someone likes me for what I say or comply to. There are a lot of times I’m grateful that someone thinks I may be anti-social because I don’t want to listen to gossip. It’s usually a hate fest anyway.
I had an oncologist tell me that girls will tell other girls how good they look when it is awful, just so they will wear it and look bad. How effed up is that? They hate each other and I don’t want to hear about it.
So get to know me. That is two fold. Don’t gossip or try to keep the conversation going for the sake of talking. The other is try to go below the surface and show that you have thoughts about something sincere, really anything. Try pets for example. How tough is that?
I’ll do my part and even put up with the introductory small talk to get to know you, but if it doesn’t go past that very soon and you start repeating the same thing, or if it’s just trashing someone else, I’m out.
I develop Mauerbauertraurigheit (definition and discussion here) quickly and am gone.
