I tend to study people, in general,...like an anthropologist studies apes, for example,...abeit missing the note pad and computer data base. I've worked with the public for over 40 years. I have seen people at their best and worst. You'd think that I would have some understanding of neurotypical behaviors,...and when I seem to think I do,...I am surprised again and again,...and realize I don't, and perhaps never will. As much as I can sit here behind a computer screen and ramble on about the some of the core differences between neurotypicals and autistics, I do realize that everyone,...everyone,...is an individual. To think that anyone knows anyone is a bit foolish, at best. My wife, she kind of falls between NT and autistic,...like she's taken the Aspie tests and will literally not qualify as either, but somewhere in the middle. That said, I think this is, in part, why we get along so darn well,...she loves silence as much as I do,...but then, she also loves going out and socializing with her co-workers and friends,...which I do not. She needs that socialization component, whereas I don't need it at all. We both complement each other in many ways,...she has her intelligences and I have different ones,...and we combine them to our benefit. I think the later characteristic about our relationship is what has made us successful,...36+ years,...we are very different people, but complement each others strengths and weaknesses. This is even more amazing to me, because as an autistic, I have never, never, never, had any idea what she was/is thinking. On the other hand, she has never given me any reason not to have complete trust in her,...so sometimes, I may not have any need to ask her what she is thinking.
I think having things in common can be a good start to a relationship, whether it be common interests,...or autism,...but some relationships can and do thrive on communication, personality traits, and trust even when there is nothing in common.
