Fleas interest me so much

Fleas interest me so much that I let them bite me for hours. They are perfect, ancient, Sanskrit, machines that admit of no appeal. They do not bite to eat, they bite only to jump; they are the dancers of the celestial sphere, delicate acrobats in the softest and most profound circus; let them gallop on my skin, divulge their emotions, amuse themselves with my blood, but someone should introduce them to me. I want to know them closely, I want to know what to rely on. Pablo Neruda
