Social reality and culture work a lot like improv comedy. We often don't know "who we are" or what's going on socially, but everyone unconsciously tries to establish expectations of one another. Understanding this dynamic can give you more freedom to change your role in social interactions.
This really made me think of Gandalf, as being a superb conductor/chef of the social web, based on very raw ingredients (Bilbo, Frodo, Aragorn).
