So, my friend was showing me around Valencia's historic town centre, we're near the Town Hall and I, bag in one hand, camera in the other, lose my footing on a cobblestone and fall over. As I fall, I try to grab onto a parked car next to me, but fail. Something flies in the air and falls in a drain, it's a UV filter fallen off from the camera. My friend helps me stand up, we rescue the filter, I want to make sure I didn't damage the camera but my friend gently but firmly pulls me away so away I limp. After a while, my friend says "You know what that car was, that you just scratched?" "Scratch? Did I scratch a car?" "Yep, big one, all down the side; the big Mercedes Benz with little flags and official licence plates...."
