I actually quite enjoyed going to an Iron Maiden concert last year, I guess I'm not your typical person with AS, because I quite like crowds. I would much rather be in a crowd than walking down an almost empty street or public place. When there are just a few strangers around people make eye contact with you, they look at you and I hate that. When you're in a crowd you blend in, you're just one of the crowd, and I love that. Nobody really pays any attention to you, nobody really looks at you or talks at you because they're all too busy watching something, or concentrating on where they're going, or full of anticipation. I like a constant buzz of noise, I can't stand silence. It's just sudden loud noises, like shrieking or screaming that I can't stand.
I have a friend who's very close to my age, and he was diagnosed with AS when he was 8. He's down the pub pretty much every night, and really loves that people accept him there, they find his quirks funny and entertaining, and he loves that. Though you could consider him to be quite extroverted, even though he has AS. There are as many different types of people with AS, as there are NT's.
