It is an original piece of writing. The good thing about writing poems, compared to narrations, is that you express more of your feelings to the poem. While in narration you have to write a lot of text to depict a situation and describe feelings of others. Whereas, feelings, emotions and the inner side of the author is directly revealed and exposed to the readers. Moreover, poetry makes people think about the writing. And sometime some lines can be very powerful and have impact on other people as well.
