The Seamstress and the Wind by César Aira:
Night fell and he drove on and on, with the horn in front . . . because he’d put the armadillo’s tail-cone on as the nose of his vehicle, that is to say he’d screwed it to the opening in front. It looked good, he thought; he’d done it only for aesthetics, not aerodynamics. What he liked most was that it entirely changed the appearance of the remains: with the horn in front it didn’t look like an armadillo anymore. It made him think how easy it was to change the appearance of a thing, what seemed most inherent to its being, most eternal . . . it was completely transformed by a measure as simple as changing the placement of the tail. How many things that seem different from each other, he thought, might actually be the same, with some little detail turned around!
