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.
“My father had left behind an old piano. My sister was already going to school, my mother was out working, and I stayed at home alone with my adorable grandmother who understood nothing I said. It was so boring that I stayed at the piano all day long, and that saved my life.”
“Therefore, if God existed, only in one way could he serve human liberty - by ceasing to exist.”
