        Recuerdo de Leonor

        Una noche de verano
        -estaba abierto el balcn
        y la puerta de mi casa-
        la muerte en mi casa entr.
        Se fue acercando a su lecho
        -ni siquiera me mir-,
        con unos dedos muy finos
        algo muy tenue se rompi.
        Silenciosa y sin mirarme,
        la muerte otra vez pas
        delante de m. Qu has hecho?
        La muerte no respondi.
        Mi nia qued tranquila,
        dolido mi corazn.
        Ay, lo que la muerte ha roto
        era un hilo entre los dos!

                  A. Machado
