All week she's cleaned
someone else's house,
stared down her own face
in the shine of copper-
bottomed pots, polished
wood, toilets she'd pull
the lid to--that look saying
Let's make a change, girl.
But Sunday mornings are hers--
church clothes starched
and hanging, a record spinning
The italicized one-line stanzas in the poem create and adjust the overall rhythm. It’s a way to break from the metered paradigm while still fine-tuning an organic sense of pace and timing. 
 These also serve as very brief snippets of insight from the woman’s mind. It’s not enough to clarify or flesh out the other parts of the poem – if anything, they inject ambiguity. But they do provide a different, less removed focalization that can take the verse into different directions. 
 For instance, what is this change she’s urging herself to make? What kind of tone is this – serious? Wishful? Ironic? Practical? Why?
