Driving to work today was a bit interesting. I was in quite a big queue of traffic and in the car in front there were two guys - from what I could see the driver was quite young, blond and his passenger was a more middle aged guy. I was waiting in the car for the traffic in front to move on for a good 3-4 minutes and this young guy was just looking at me but through his mirror and sort of smirking/smiling. He kept on until we moved off! Bit weird feeling really. This happen to other people?
