The following is an answer and/or comment by inhahe aka ColorStorm (inhahe.com - myriachromat.wordpress.com).
A long time ago it seemed that other people weren't like me at all, and they were all different in the same way (i.e. not different from each other, but different me, at least in a particular, prominent trait). So eventually I decided that the only way I was going to make it in life is if I understood how others thought. So I started putting myself in the heads of people around me, and just thinking.. "if I had said what he just said, what kind of mind would I have?"

So somehow that made me more normal, and better able to relate to people, but I lost the ability to see their weirdness or even their retardedness (which is also something I used to notice about other people. To quote what I said in IRC yesterday, " when i was growing up i was always astounded by how dumb people are. it was a bit of a contradiction to me, because they looked like real, intelligent people, but as soon as they talk it's like.. wtf")

Also I can no longer see how insanely huge everyone's egos are, it used to be so obvious that I felt alone..
