We were dancing at Boogie Wonderland last night, my friend who's getting married and her friends, and I had a minor epiphany.
I reckon there are two broad categories of dancers in nightclubs - interactive dancers and trance dancers.
Interactive dancers are the ones who are quite unselfconscious, throw in the kind of flamboyant moves that are fun for everyone else to watch, and actively dance with people. They are the ones who start conga lines or get their friends to take turns moonwalking in the middle of the circle. If you're dancing in a group and the interactive dancer leaves to go to the Ladies', much of the loud, silly fun you're having suddenly evaporates until her return.
Trance dancers are selfconsciousness dancers; they'd prefer to have at least one cocktail down their gullets before stepping out on the dance floor. Once there, they tend to dance as though on their own. This is because they need to zone out a little before they are comfortable with moving to music in public. They are likely to stay on the dance floor until it's time to leave, because it's easier than having breaks and then deciding whether the next song is good enough to dance to.
I bet you can guess which one is me.
