At night in the office... I was struggling with my PC. I heard a clattering sound coming from the office's archives, where no one should be. Thinking that it was just my imagination, I turned to the PC again. Then, this time, I heard a lewd sound: "Clack... Aah... Aah...". I felt that this was not normal, and cautiously headed towards the archives... An hour later, I was lying on the floor with my lower body exposed, like a boxer after a match.
