Ultimately, "El Niño, El Zorro, El Topo y El Caballo" offers a powerful exploration of what it means to be human. Through the relationships between these four characters, Mackesy shows us that it's okay to be vulnerable, to not have all the answers, and to seek comfort in the company of others. As El Caballo so eloquently puts it, "What do you do when you can't do anything?" The response is both simple and profound: "You do what you can."
