I love to dance at clubs, but I'd rather go with a group of friends than a significant other. Actually, I just like dance period, of any kind--I've studied a few different styles and would do more if I could afford it :\
I like dancing - hell, I write about dancing in my fiction. And me with two left feet, too. Anyone I've ever been with refuses to dance, though. Which I think is a little disappointing, as I think men who dance (especially ballroom dance) are sexy because of their classiness. Trying to get a straight guy in America to do that now is impossible. *sigh* Standards have fallen.
I have no idea what's "in" or "out." Nor do I care.
I'm not a big fan of dancing. I'll dance in my kitchen when I'm cooking or in my driveway while I'm goofing around. I don't care to dance in public. What other people do is up to them and doesn't matter to me.
