I saw a dog recently. He was on his way to work. It was a sort of stuffed sofa cushion, decorated with long tassels of skin, wobbling down the Leipziger Strasse in Berlin. He was dead serious, he looked neither to the left nor to the right, he sniffed at nothing, and certainly did nothing else. He was definitely on his way to work. What else could he have been doing? Everybody around him was doing it.
