A nation respecting its teachers

During childhood I often heard the story of a policeman who stopped the traffic to let a professor cross the street. Today I saw it in Germany. I was sitting in a bus coming back from the university, when a couple of professors got out of the car parking talking to each other. They were about to cross the road but then saw the bus and stepped back. The bus-driver stopped the bus and asked them to cross the road, even though it was no zebra-crossing. Normal cars may stop for pedestrians without a zebra-crossing, but buses never stop. This was the first time I saw this.
