I don't dance. I tried it once and found myself observing the others, attempting to understand the point of such an activity. I can easily tell you my history of appearances at dances:
1. When I was 15, my best friend convinced me to go to the Jamestown Sports Complex, which hosted dances on the gym floor on most weekend nights. That was a really difficult environment for me, because I didn't understand the activity.
That's it.
(The time I made an actual attempt to dance was at age 18, while I was at work. The people throwing the party wanted me on the dance floor, and my co-workers gladly prodded me. Luckily, there were enough people that after standing for a few moments, scarcity lent a hand to my existence.)
Now that I think about it, I can recall going to a nightclub when I was 29. It was very small and a few people were dancing. I only went out because a co-worker had turned 21 and I was asked to monitor him. When I was 21, I once passed through a nightclub, because I needed to use the restroom. I really do not like those environments, with people moving about sporadically. Also, I would never drink alcohol in public, since the reduction of awareness correlates very well with easier victimization or a free ride to the police station.
