On a rainy day, as I entered a bar in a former East Berlin bar, I heard an aggressive female voice yelling at me, in German which I didn’t understand. The woman (Mandy) who was yelling at me also gesticulated wildly, pointing at the door. While I didn’t understand what she was saying, I could feel the aggression and almost anger in her voice.
For the following two weeks, I went to the bar every day, trying to figure out why. Eventually, I got the clue. And I hired two actors to re-enact the scene in multiple versions.
