That kind of thing happens to me too. Some of it is cultural I think, NT culture that is. Some pretty girls think they are superior and can act in any way they like (they will lose their looks like everyone else)
I still cringe about someone the situations I have found myself in.
Someone I once knew a little was in car outside my house, I had not seen him for a while so I went outside to say hello. I went to the car and knocked on the window and asked was Chris there. I still really don't know what happened, they denied he was in the car (it was night) but I could hear them all falling around laughing and they were saying things to me which I did not understand. Finally I worked out they were making fun out of me so I went back in the house. Until I was diagnosed I was ashamed of myself for being so social awkward. That incident was 30 years ago but I can still remember how I felt once the penny dropped that I had not got the wrong end of the stick, they really were making fun of me.
