with "what is happening now," the audience is oneself
note that this could involve multiple levels of Moffettian abstraction: "within the frame of what is happening in and around me (introspection and observation), I may embed what happened (memories triggered by ongoing stimuli), what happens (general reflections prompted by the scene) or what may or could happen (theoretical considerations also generated of the moment)"
"memories, generalizations, and theoretical thoughts are a part of the ongoing inner action"
There is also "telling the [...] experience to a friend some time later in conversation" and then writing it "in a letter to an audience more removed in time and space"
"Compare [...] the changes that must occur all down the line when I write about this [...] experience in a discourse destined for publication and distribution to a mass, anonymous audience of present and perhaps unborn people"
"Increasing pluralization and therefore generalization of the second person" (as in this sort of public address) "tends to enforce higher abstractions, formal writing of the sort one would publish"
