I happened to catch the tailend of a programme about the World Service hosted by Terry Waite. He was talking about what the World Service meant to him during his captivity (he was given a radio during the last few months). Then he went on to explain how he would picture the presenters and newsreaders and continuity men in the studio and how important imagination had been to him while he lay there in his cell chained to the radiator. Yes. I understand. Even in this relative comfort and freedom imagination can still take us to those places and people we cannot at present visit. He is a lesson to us all to be thankful, to be grateful for small mercies. Always.
