I arrived at Cologne already on saturday, November 11th… (knowing laughter from the audience) …and at 11 o’clock, carnival started. People were happy and had fun. Cologne is a very beautiful city. But later, wandering around, you could spot some places with broken glass and garbage people discarded. From some distance away, though, Cologne was still looking as nice as usual. A “vista”, in the english language, is something that looks beautiful from some distance away, but if you come closer, you’ll start to see the broken glass and the trash that’s there.
