But it has also gone beyond emails: “A few months ago I was with my wife at the supermarket, and suddenly someone tapped me on the shoulder,” Keilaf (40) recounts. “I turned around, I saw someone I don’t know and whom I’ve never met, and he asked, ‘Why is the stock going down? What happened yesterday?’. I was shocked.”
