I don't know whether a poem has be there to help to develop something. I think it's there for itself, for what the reader finds in it.
“I am convinced that military action will not prevent further acts of international terrorism against the United States.”
“I hate modern car radios. In my car, I don't even have a push-button radio. It's just got a dial and two knobs. Just AM. One knob makes it louder, and one knob changes the station. When you're driving, that's all I want.”
