Did he get into an accident?” “No, it’s that he’s hard, but the other guy’s…a cycle path.” “Yes, but why is he frightened of cycle paths?” Sometimes I lost sight of whether this was my hobby or a punishment I was inflicting on myself. “No, it’s a pun, Alex. Because ‘cycle path,’ if you say it fast and in a sort of Cockney accent, sounds a bit like ‘psychopath.’” “Oh.” He thought about it for a moment or two. “I’m not sure it does, actually.” “You’re right, Alex. I’ll do better next time.”
