I worried over that for a while. A teacher had spoke about it once, and it caught my interest. When I was reading about the symptoms I kept thinking "That's me"... but it isn't. I'm not super-smart, I have friends, I participate in the "contagious yawn" (social cue), and I'm mastering body language, I have a love/hate relationship with change, I don't lack empathy (unless it's someone I don't like), I have a GREAT sense of humor and I'm great at spotting sarcasm. I did speak unusually for a kid, and I still usually avoid eye contact as much as possible, but I'm no longer freaked and worried about being autistic. It's just not me.
