I have my kids to blame, that is certain. There I was, last Christmas, in this auditorium, listening to the crunching of popcorn from my son on my left, and the slurping of soda from my daughter on the right, trying to behave like a responsible father. The lights had dimmed and we were being inflicted with the inevitable advertisements and trailers. When, at last, the fan fair that accompanied the main feature at the cinema trumpeted out of the speakers an anticipating hush spread around the audience. Even my daughter took a break from her munching.
