I have never said the words ‘free gift’. It would seem a sinister thing to say when gathered around the Christmas tree. ‘Here’s my free gift, and, as an added bonus, here’s a festive Christmas card.’ People would think I’d gone mad. Yet, if you wander into a shop or make the terrible mistake of turning on the television or radio, you will hear of havens that are safe, co-operation that is mutual, and prizes that are, it turns out, to be won.
