Interesting. I have actually never walked away from a dance because I was being hurt. I just suffered through the dance and resolved never to dance with the guy again.
The two times I have left a guy on the floor were because he was being unimaginably creepy. Both of them were older. One of them was staring at my chest and appeared to be touching his own genitals while dancing. The other one was trying to dance a cha-cha way too close in this weird, jiggling, I-don-t-know-how-to-dance way while staring fixedly at my right kneecap. That was the one where I overreacted to the injury. (The first one I left without an excuse.)
