"The Rhetorical Situation"

Bitzer's "The Rhetorical Situation" is a discussion on how important situation is to rhetoric. It was a bit of a challenge to read and understand in my opinion. From what I was able to gather, he explained that rhetoric is a response. He explained that an "exigence", an audience and constraints must be present  as constituents of a rhetorical situation.

A line that I thought was interesting and that I related to was "...we all have the experience of creating a rhetorical response when it is too late to make it public." I hate when this happens. I am the worst at this. I can never "think on my feet." I always come up with a perfect comeback or response minutes, hours, or days after it is too late or awkward to use it. I guess I'm not a quick thinker.
