Yes, I was trying mostly to talk about #2. I like the dominance frame because I think this kind fluid dominance roles is the something like the Proper Use of Dominance. Dominance as enabling swift changes status to track changes in legitimate authority.
Seems like that wasn't really very clear though.
I think I want to additionally emphasize, people being comfortable temporarily taking responsibility for other people. Sometimes I want someone to come in and tell me I have a problem I don't see and how to solve it. I try to do this for others because I think its one of the most valuable services I can provide for people. Letting them see outside themselves.
