I hadn’t noticed him at first; I was listening to a podcast of This American Life, the one about Father’s Day, and it took a while for me to realise he was actually trying to speak to me. The man was smartly dressed, wearing a dark suit jacket over an open-necked white shirt. He didn’t look like a weirdo, but you never know. I took one earbud out and turned towards him.
“You have a lucky face,” he said.
