Am I retarded?

Am I retarded?  One of the funniest thoughts that I have had is the thought that most people that are retarded don't know they are retarded.  Their perception of the world is generally skewed and they see themselves as no different.  I know this isn't always the case, but it's a gross over generalization, I am aware of that.  I used to wonder if maybe I was retarded and didn't know it.  Maybe my "friends" were really personal care workers and I was simply their means to financial support.  Obviously this isn't the case but I do wonder how this is perceived by people who are in this situation.  This also brings me to my next question.  Do crazy people know they are crazy?  I suppose some of the difficulty is in defining crazy.  Some do some don't in my opinion. I was visiting with someone recently who said "She's a crazy bitch, I'd like to ask her how long the longest friendship she has had is".  This is extraordinarily ironic because I'd like to ask the same question of the person I was talking to that made this statement!  So obviously she doesn't know she's cray.  Perhaps that has some to do with narcissism though.  Both cray people in my current discussion are narcissistic to some extent.  Anyways, that's just some interesting thoughts I have been having today.
