      Here is the text, inside <input></input> XML tags:
      <input>
        To perfect his horror, Caesar, surrounded at the base of the statue by the impatient daggers of his friends,
        discovers among the faces and blades that of Marcus Brutus, his protege, perhaps his son, and he no longer
        defends himself, but instead exclaims: 'You too, my son!' Shakespeare and Quevedo capture the pathetic cry.

        Destiny favors repetitions, variants, symmetries; nineteen centuries later, in the southern province of Buenos Aires,
        a gaucho is attacked by other gauchos and, as he falls, recognizes a godson of his and says with gentle rebuke and
        slow surprise (these words must be heard, not read): 'But, my friend!' He is killed and does not know that he
        dies so that a scene may be repeated.
