Recently, some of the children’s friends came to visit. In the car on the way home from school, we saw a Christmas advertisement for Coca Cola with a happy Santa and a large lorry. “Coca Cola is poisonous,” opined our five year old visitor, “we are not allowed to drink it at home.” “No, it is not poisonous,” said his eight year old brother. “Do you know,” he asked me, “where Coca Cola is mostly made?” Without pausing for a reply, which was as well, really, he continued, “In South America, in Brazil and they won’t let their workers unionise.” This conversation was somewhat beyond Daniel but he was trying hard to follow the general gist, unlike his sister and brother who had lost interest. He turned to his little friend, the five year old, and asked anxiously, “Is Santa really poisoning the Coca-Cola?”
