As a young lad, I travelled with a close friend to Germany, where we hired a car. Due to bad planning, we ended-up in Frankfurt late at night on the day before our flight back, with no hotel. There was a 'messe' (exhibition) in town that week and all the hotels were fully booked.
Being 'young and brave', we thought we'd sleep in the rental car at the airport, then in the morning hand it back and catch our flight.
I parked in front of Departures around 1am and my friend immediately fell sound asleep. I didn't manage to catch much sleep though.
At 7am a uniformed German police officer walked up to the car on the passenger side, bent down and peered inside, and on seeing my friend asleep tapped lightly on glass with his baton and signaled us to move on. Which I did, and thought nothing of it at the time.
However... my friend woke-up with a startle to see the German policeman tapping on the window with his baton, which gave him quite a fright. To this day - we still keep in touch - he describes the moment of terror when a Nazi officer attempted to adult him with a baton.
This is a true story - and the moral is that different people perceive the same events in completely different ways... beauty is in the eye of the beholder, and often so is offence.
