Pretending to be normal, that's it.
I really cannot overstate how much I do not like being around people. I can't describe it in terms exact, but people can study you, learn things about you and become friends with you. The next second that same person could, belittle you, make you feel worthless, beat you, bloody you and make a showcase of everything you stand for, all in the name of moving up a few pegs on a social ladder, or even worse "a bad vibe" or "ick". Animals don't do this, and if they do it's for their own survival. Pestering another over a claim about them, only because it's became known due to it falling down the social vine, is not survival, it's cruel, selfish and unfair. Animals don't engage in prostitution, animals don't read and watch porn, animals don't run monopolies, animals don't feed other animals poison, animals don't engage in the noob liar shit of the modern world, they just survive through any means necessary. Human society a failed experiment.
