How did you know Mrs Barnaby was the one?, he asked him one day, out of the blue. Question was so unexpected that made him gasped and slowed down. How did I know? Ben continued to walk, and passed him, briskly. She told me, he replied. At first, he thought that was the most reasonable thing to say, but, to be honest, he couldn't remember. Or, maybe, he did not ever know. He resumed walking, watching Ben's shoulders and thinking that, after all, maybe Sarah was wrong.
