Day 6 of this year's Mormon Lit Blitz is Merrijane Rice's poem "On the Death of a Child."
People tend to read poetry more carefully than other forms. Even live, people listen for the nuances of a poem in a way they don't tend to strain for detail in a fiction or essay reading. One way to use poetry, then, is to compress meaning: to evoke a lot of different memories and associations with a single phrase or line.
How does Merrijane do that?
What do you with pain that comes and sits on your chest and stays?
How do you help and stand by someone who is dealing with a major source of pain?
