With the feast behind us, and hopefully some well targeted toasts given, the Friday after Thanksgiving becomes a day to recover, relax and gear up for the holiday barrage. This year, as the season bodes poorly for commerce, perhaps it's best to focus on those intangible things that give us great value and joy. Although I have called  your attention to our music documentary Soweto Strings before, I would like to approach its virtues from another angle today. The film, about a classical music school for South African children is noteworthy for the way it shows how music can flourish and change lives no matter where it finds itself. But it is also about a remarkable teacher, Rosemary Nalden.  I have been lucky to have had some inspiring teachers in my life, and she reminds me of them, with her fierce devotion to education, and her delight at the receptive nature of her pupils. So may I suggest, as you watch Soweto Strings this week, that you think on some of the pivotal teachers in your life, and say a private "Thanks" for their efforts.
