Aracelis Girmay’s poem “Elegy [3],” from her second poetry collection, Kingdom Animalia (BOA Editions, 2011), begins with a question: “What to do with this knowledge that our living is not guaranteed?” The poem’s speaker finds hope in the natural world as a way of answering this existential question: “Perhaps one day you touch the young branch / of something beautiful. & it grows & grows.” Write a poem that seeks to answer what it means to be impermanent. What do you wish to leave behind?
