Clara was standing on the station platform waiting for the next train. As she had often done recently, she passed the time with Snapchat. She held her telephone high in the air, so that it looked as if she was filming the surroundings. She was separated from the next platform by a deep trench and two railway lines. The platform was almost deserted. Far away stood a man watching Clara with a sour expression.
“Hey you“, he called in her direction. „What are you doing? Stop filming”.
