I've just seen this posted on Reddit and I totally relate!
As a child I was "gifted" always ahead of my peers and didn't enjoy playing with them. I would much rather talk to adults about all sorts of topics.
As an adult I just don't relate to other adults at all. I was just reading a post on here about things that bring you comfort and I just feel so alien to all the other posters.
I enjoy pastimes which are seen as childish, my clothing is seen as childish and my body language too.
Anyone relate?
