There's this girl that sits next to me in one of my classes and she's pretty big, which is obviously what I'm into. I'm pretty socially autistic and keep to myself, especially around girls, but I've spoken to this girl a couple of times and no matter what I say she just laughs and thinks it's the funniest shit ever even when it's not, which makes me think she might like me. I'm pretty skinny and I guess a little above average face wise, my mommy says I'm handsome. So should I just face my autistic fears and go for it and ask out this girl? Is her laughing at my jokes a sure sign that she's into me?
