Just like fiction, the poem is written in a specific point of view:
a point of view determines how close the reader is involved in the poem.
First-person (I, me, my, we, us, our) will draw the reader into the poem.
Third-person (he, she, it, him, her, his, hers, its, they, them, theirs). will create more distance. The reader will be an observer.
Second-person (you, your) The speaker is speaking directly to his/her readers. Using second-person point of view, however, has to be done carefully as it is a more advanced skill and can be done poorly by an inexperienced writer.
