Consider Refrain. Ammons uses the phrase "when you consider" as a refrain. It appears often throughout this poem, reminding readers that they are being presented with a subject that they might not have thought about before, or at least have probably given too little consideration. Repeating a refrain often works in poetry in the same way that it does in music: regardless of the actual words being repeated, the very act of repetition gives readers a sense of the author's control, reminding them of the fact that somebody has arranged the thoughts being presented. In "The City Limits," this refrain establishes a voice for the poem's speaker. It is a gentle and thoughtful voice, one that is not about to rush readers to see things a particular way but is instead offering them suggestions.
