You need poetry in your life. Your soul requires that you step out of the banal. Your soul requires that you connect two seeming disparate objects. Metaphor arose from a need. It wasn't the metaphor's need. It was your soul's need. You knew your presentiments of life were not balanced. You knew your view of life was lacking. You knew that poetry speaks more truth than fact, that poetry is not truthfully exaggeration, but that a dim view of life is woefully overstated.
