For me it was the opposite, I was encouraged even demanded by others to be more social, more open and assertive. And I would run and hide in a corner behind doors so nobody would find me.

I always preferred thinking and dreaming about things than actually doing them, when it happened it always felt a bit bleak and empty. I had few bad experiences with peers (but everyone has them growing up). I even thought to a point that other people fake their emotions too much, because they always appeared over the top for me but I guess it me that just feels way less than average person does.
Honestly I doesn't bother me much to be alone (I enjoy it much more than being in company that isn't intellectually stimulating or is emotionally too demanding), it just draws too much attention if people see how empty my life is, and that makes me uncomfortable. I need a front to hide behind and appear regular.
