Ha, thanks for all the support - it's been a rough week!
The woman who was saying the stuff - I don't think she was really trying to be mean, I think she was trying to be sympathetic, but she didn't understand. Part of the problem and the reason that she was discussing it with me was that the woman is very clingy. They used to be in a class together, but the class ended and this woman just keeps calling her, pretty much unwanted. She's always very kind to her, which is probably why she keeps calling back.
Maybe this clingy woman is very sad and complains to her, I don't know, but whatever - people keep reinforcing this idea that other people who are alone a lot are either crying constantly, longing for companionship or plotting to kill somebody. There are SO MANY people for whom this is not true.
The other big one is that if you can't make friends you are a horrible person, not just that you could be a wonderful kind person who sucks at social skills.
Those are two of the problems that I ate most about Autism - and they're not really about Autism, just people's perception of it.
