Four times at least (as I recall), I tried to open the wrong flat, forcefully trying to get my key into the lock. All the hallways and stairwells are identical in the housing estate in that precise and efficient German fashion. After a night out getting lubricated with the typical 1 liter beer steins it can get all so disorientating. I got the shock of my life when my door was sealed off by the Polizei before realising "Shit, I'm in not just in front of the wrong door, I'm also in the wrong building."
