I find it necessary to be socially available to my friends (unsurprisingly they're most ASD) in order to maintain a social identity. We tend to go into our personal soliloquies and appreciate each other for what we are. After enough "influence" we explore neighborhoods that require some retrospective upon themselves.
We call it artistic vandalism and adventure (trouble) seeking.
Without that I would just read and read and read and...
Family gatherings, professional performances and my hobbies requiring social participation (judo, dancing, singing and theater) don't count in this regard.
I like to dance (been a performer/martial arts type most of my life when it comes to self expression using all of my body movements, excepting the bowel and other physiological ones) in order to manipulate people into thinking about the details that make that damned larger picture (I don't hate people per say, just their monotonous perception of what's right and wrong).
I enjoy that feeling when people just give me space on the dance floor, so that I can express my stimming in a creative way.
This happens a few times a year and that's all I need.
Otherwise socializing is a moot activity for myself, though sometimes I wish I wasn't so damned "stubborn" about not caring about some ladies' attentions (carnal pleasures when experienced with a woman I really enjoy being with help me deal with that lonesome existence I deal with most of the time, as rarely as it happens. No sex for the previous 5 years is my count so far).
I'm just glad I had the chance to develop a sensitivity for beauty, which helped me appreciate life and people for what they are and not for what I want them to be.
