The poem's structure is unlike any form we've seen before, it's very interesting to read and hear the pauses in every sentence because of the dashes and the random capitalization of certain words

responsibility in friendships

I find it interesting that Elizabeth Bishop uses polysyndeton within the poem. Using 'and' frequently instead of the use of commas. Normally we are taught to not use connecting words frequently and so close together so I always find it fascinating when poets use polysyndeton within their writing.

Interesting how the poem's sentences continue while being split between stanzas

Graves uses polysyndetons within the poem by repeating the words 'enclosed by'

Manley uses an alliteration here, focusing on the W sound and repeating it throughout the sentence

There is obviously a difference in the rhyming pattern of Donne vs. that of Shakespeare. His (Donne's) rhyming scale is A,A,B,B vs Shakespeare's whose is A,B,A,B. While reading this poem I continued to get the sense of a very deep connection between the two lovers. One word that stood out to me the most was 'mingled'. To me it just shows the closeness of the two lovers and how even their blood mixes together and brings them even closer.
