When Koen squeezes his fists together, he comes to an abrupt halt in front of the door I sit behind. We meet at the Shell station, a person I have never seen before, with a twinkle in his eyes, moving with the ease of an adolescent youngster, one of 45. He’s having a bright smile, and when I see him I jump of my chair to greet him. Funny, not to know a person except by typed words over Messenger.
