Before my wife and I met she had a single date with someone. The date went fine but she found him to be over bearing, (he pulled his dick out for her to touch as an example) so they didn't go out again. They remained friendly until 2 weeks later when he murdered his next date and set her on fire. He is now in prison for those who may want to know.

Edit Update: He shot and killed her in front of her kids and then set her house on fire. Sorry for my (partial) inaccuracy.
