What is a short summary of Powerless Structures from the collection, Float?

"Powerless Structures Fig. II (Sanne)" is a short chapbook consisting of a poem written in couplets, which details the connection the speaker — who is presumably Anne Carson — has with a woman named Sanne, who has recently died "of alcohol and indescribable longing." This chapbook is concerned with grief and grieving, and provides two different perspectives on overcoming disorder: the first suggests that form is capable of overwriting, or overwhelming grief, while the second suggests that grief overwrites, or overwhelms, form. Carson leaves the exact significance of this chapbook vague so that it is up to the discretion of the reader to decide what, exactly, "Powerless Figures" has to say.
