I think I've shared this before, but there was a ridiculously hot girl that went to my community college and had autism. She really wanted to go out, and would try to be "playful" with her flirtations, but her tone was so dry that others would often confuse her with being mean.
Then she'd apologize and message me all day, because she wasn't aware that some of her comments were inappropriate to others, to the point where it became obsessive. That is actually what scared me off more than the autism, was the obsessive behavior - the constant messages, waiting for me to come to the student life office, writing my name on stuff at the student life office, etc.
But - wow - she was and still is the hottest chick ever interested in me.
She also did weird stuff like read Nicktoons fan fiction... all the time. She'd find these sites full of Rugrats fan fiction and read them for hours. It was weird.
