Once, it was a disaster for me. I remember lots of people thinking that I would get along really well with this mentally handicapped girl at my high school, it turned out I didn't get along with her at all. She turned to to be rude, manipulative, mean, nosy and lying. She would look into rooms in the school and make faces at people and laugh just to annoy them. She would ask people personal questions and get mad if they said they didn't want to talk about because it was personal. She got mad at me because at Halloween she wanted to trick-or-treat with me and I don't trick or treat and I said "I'd love to but I don't really trick or treat anymore". She would always get annoyed when people said they couldn't hang out with her. Other people have had issues with her too. Also, she was one of those people who think if it was OK for THEM to bully another person, but doesn't think it is OK for ANOTHER PERSON to bully them. I have gotten along with other mentally handicapped people though.
However, not every situation has been like that. I have an acquaintance who has moderate autism, enjoyed some of the people at the camp I went to for autistic children last year and had a casual friend with autism when I was about 10.
At the moment, all of my close friends are older NTs, I have few acquaintances who have disabilities though. They are all my age.
