I walked back to the entrance of the industrial park and saw the lowered blinds in the porter’s lodge. With the annual Christmas whirl, I had forgotten that Biefer and Sandoz were both retiring at the end of the year. A month before, someone had organized a collection to buy them each a retirement present. I had contributed, signed a couple of cards, and then not given the matter any more thought. Now I felt sorry I hadn’t said good-bye to them.On the glass door of the little porter’s house was a map of the premises. Below it was a list of numbers in case of emergency: fire, police, ambulance, and a number for the administration. In a transparent document wallet next to that was a letter from the administrator. He wrote to wish all the tenants a happy holiday, with many happy returns for the New Year. The letter was decorated with an illustration of a fir twig and a candle.Time was, hundreds of people had worked in the factory, but after production and development had been contracted out abroad, the industrial park emptied, until there were only the two porters left.
