The kind where if you have to be around people you feel more comfortable in a group than with just one other person?
I get nervous around "dead air" if I'm with people so if I'm the only other person I feel pressure to be interesting and it's exhausting. If there's a group of people it's not so bad because it divides the responsibility of being entertaining around all of us so I don't have to worry if I'm boring. I can just chill and let other people talk.
Plus I find I'm better at bouncing off of others than initiating conversation.
Performing arts do the same thing. Silence is a part of a change in mood and conversation, nobody can effectively make a choice on stage without experiencing it. Sometimes it's for less than a second, sometimes it lasts minutes but it always preceedes anything important. In music there is something similar where musicians will try to be loud, everything always loud all the time, but what was meant to be epic music becomes a drone of indecision.
Some people really struggle with putting their mark on a situation. There is a timidity that most people have that must be beaten out of you before entering the ring, or stepping onto a stage. It's so helpful and freeing once you finally get it.
Damn, that's an entire dimension and perspective I hadn't really considered. I've made the connection to dancing in other ways, but didn't think about the implications of both being forms of expression
