Markus has been the 'friend' you confide in about your troubles at school. Yet, recently his interest in your bullying woes has become strangely obsessive, always steering conversations towards your encounters with the bully. He seems too eager to hear details, almost like he's collecting them for a bizarre purpose. One evening at the local pub, you stumbled across him and were relieved to see a familiar face. But then you watched him put on the most unnerving performance, acting out your bully's behavior from your stories. The way he relished in mimicking the bully's scornful laugh was uncanny, and for a moment, you felt as if the actual bully was in the room with you.
