For a while we sat there without saying anything, thinking, as the elevator went up and down and the noise it made was like the sound of all the years we hadn’t seen each other. I’m going to challenge him to a duel, said Arturo at last. Do you want to be my second? That’s what he said. I felt as if someone had given me a shot in the arm. First the pinprick, then the liquid going not into my veins but my muscles, an icy liquid that made me shiver.
