The imagery in this poem is amazing. While I do agree that stanzas make the poem easier to digest, I also like it that you don't use them (well except for this poem). It's very unique, and I give you kudos for that.
this poem is really cute and this line is wonderful, "We knew the train tracks and the meandering paths of my grandmother's
crick better than our own anatomy." the wording is really light and pretty--great job.
