Getting to know a complex person is like uploading an advanced computer to another computer, or more literally, uploading a mind to another mind. It's difficult. Really difficult. Because you only have actions and countless conversations (words) to accurately convey who you are.
If people in your family and the people judge you for what they do understand, you won't open up and they're not worth your time for shutting you down. If they can't understand, it's not necessarily their fault. But you have to realize that some people cannot stomach extremely bizarre personalities. Often times, only one person, the person closest to you - be it a best friend, close family member, spouse, etc who will know you and understand you to such a deep and profound level. If you don't have that person, it might get really lonely and emotionally painful at times. So sometimes we have to settle for the people who are there for us, who genuinely want to get to know us, and try to get to know us, even if its not at our ideal level. And some people may seem superficial, but aren't, because they've gone their whole lives showing parts of themselves that are acceptable to be shown. They're used to people, including family, not knowing them in the truest sense of the word. You can't say someone is superficial just because they seem a certain way.
And some people are naturally extremely hard to get to know. Especially people who value their privacy. Its not because they're hiding secrets, they're just very complex, and can't help it. Or they haven't figured out who they are. How can you get to know someone who doesn't even know himself/herself? So you have to take it slowly. Wait for the moments where you can talk one-on-one. Also, a lot of getting to know a person is to make it apparent based on your actions. You can say who you are all day long, but until what you say becomes apparent through some of your actions, it doesn't matter- people have to see who you are; people are visual creatures. You might be thinking 'that's ridiculous; how do you show a person who you are?'. Telling good jokes says that you have a sense of humor. Insightful comments say you are insightful (instead of you saying: 'I am insightful'. It's too blunt, and any idiot can say that). Asking seemingly irrelevant questions about people mean a lot and are helpful to getting to know other people. So, if they're not asking you questions and/or not observing who you are, do they really want to get to know you? It would be questionable. And it's not just other people. It could be you. It's easy to point the finger. But, the real question is this: are you asking questions to get to know them better? Asking personal questions - according to how well you know them and how well they know you - will encourage the reciprocation of effort in connecting. In other words, asking them questions about them makes them want to ask questions about you. Although some individuals don't seem to grasp that concept.
And I think, as aspies, we tend to miss how much NTs see, because they don't always openly acknowledge what they see. It's also sometimes hard to find someone we will connect with, and it's hard because not everyone thinks or communicates the same way. We shouldn't info-dump everyone we meet with who we are. But little things here and there can make us easier to get to know.
