Write a villanelle, a poem of five stanzas made up of three lines each, with a concluding quatrain (a four-line stanza). Lines one and three of the first stanza are refrains throughout the poem. The first line of the first stanza is the third line of the second and fourth stanzas; similarly, the third line of the first stanza is the third line of the third and fifth stanzas. Also, the first and third lines of the first stanza are the last two lines of the concluding quatrain. Every line should be the same metrical length.
