You know, someone asked me this at work the other day.
She was talking about taking dance lessons and shit, and was shocked when I said I absolutely hated dancing and generally have nothing to do with any form of dancing no matter what the social gathering.
When she said "but you're a metal fan- don't you even mosh?" she was genuinely surprised when I said that in my mind, moshing is still in the same place as what John Travolta does in Saturday Night Fever- it might be fun to watch other, more rhythmic people do, but I'd rather prop up the bar.
