Honestly, certain people definitely attract lolcows. My dad and I have been discussing how for some reason, my family (and a lot of my friends, actually) just magnetize "crazy people" whom are usually lolcows. As in, we could be in a room full of people, or perhaps even a whole festival or stadium (since that's happened to me), and what is safely assumed to be the most hilariously batshit crazy people within that vicinity will somehow find us, even if we don't look atypical or give off any signs of "open-mindedness." It's like they have this sonar that enables them to find us. Because of this, I've been lolcow ranching for my whole life.
For instance, my mom was in a hospital and there was this lady who must've been on meth or something. My mom said it seemed like this lady seemed like she was tweaking, but anyway, she kept repeating, "I was standin' in a rain puddle when I got struck by a bolt of lightning, and then I became a born-again virgin and my cunt flew out of my mouth!" Over and over. And over. And so on. Imagine that. I might feel bad for laughing if she didn't keep trying to assault the staff/grab their nether-regions, so they had to literally detain this lady while she was screaming, "IF CHRIS BROWN ISN'T OUTSIDE, KILL ME! KILL ME!"
Needless to say, I'll eventually share my encounter reports with you.
Edited for some stupid grammatical errors.
