Scratch

How my car got a scratch on the passenger side door? No, I didn't hit anything or anyone. Happened about a couple of months ago. I had just left our apartment and turned into the road, when I saw a guy on a motorbike pointing out and indicating to me to stop my car. I checked all doors to see if they were closed properly. Yes, they were. Next I wanted to know if my indicator lights were on. No, they were not on and pointing in the wrong direction. So why is this chap stopping me, I thought. Anyway, I parked by the side of the road. This guy gets down from the bike, walks up to me and wants me to open my door. I refuse and want to know what is his problem. He starts blaming me for my "poor driving" and says that he fell down because of me and do I know driving? I racked my brain for a few seconds to wonder if I had seen him, or whether my car had made contact with his bike in the two minutes that had elapsed. No. Then what is this guy accusing me of?

Fortunately, I had not opened the windows, and the doors were firmly locked preventing that guy from getting in the car or trying to act smart. I just said, I didn't know what he was talking about, and sped off. While on my way I kept wondering if I had seen him earlier, or would see him later. When I parked my car and shut the doors, I noticed that during the couple of minutes that he was talking to me from the passenger side door, he had managed to scratch the door with his motorbike key! Possibly his idea of "revenge" - for what, I still don't know.
