Not everyone knows how to dance, and not everyone understands what goes into preparing a good dance event. I'm okay with that, as we all have different talents and backgrounds.
It does annoy me, however, when dances are organized by people who know nothing about dancing. Now, I'm not saying that the organizers need to be professional dancers. However, when they fail to understand such simple niceties as keeping the dance floor dry and mud-free... well, that's just dumb.
What's more, they typically cater to the lowest denominator. That's why a lot of dance parties have plenty of mindless line dances such as the Cupid Shuffle and the Cha Cha Slide. Don't get me wrong; I'm okay with having some of these dances, especially for the benefit of people with no dance expertise. However, when you have these kinds of dances over and over again in the course of the night, it gets to be a bit much.
