Has anybody read impro by Keith Johnstone? He’s got a write up in there about status, and how before they “figured it out,“ the actors couldn’t make believable scenes of “everyday conversation”. Then, after some play or another he hits on the idea of everybody trying to make their status just a little above or below the other person’s status in conversation. Suddenly the acted conversations became “authentic”. This post seems to be a similar take at a different scale and perspective. Interesting stuff.
