Well, like I posted in the sx thread, I think a big part of my so awareness and prioritization was my wanting to do my utmost not to be like my sp/sx mother, who embarrassed me in public or social settings growing up due to her being oblivious to other peoples' body language and social dynamics in general. So I had a strong desire to not be like her. (am not saying I don't have some similar issues, as maybe I do, but I'm saying via observation I saw this stuff unfold) Also, my family was for the most part very socially isolated and closed off, and that always bothered me to a degree, and I felt I was 'stunted' and lacking in those skills and awareness growing up. So via observation and preoccupation with that I think I became a little hyper aware of social stuff and relationships as a result. (fwiw my dad is either an sp/so or so/sp, but, I am of a family of all introverts)
(Also, some context, there was never a lacking in sp elements, I felt 100% secure on a tangible safety and provision level while growing up. Social element was very much lacking, and to maybe an equal degree, sx intimacy and rawness was lacking, though, social was maybe felt stronger by me)
