Beginning with the inevitable disappointment of my ‘Secret Santa’ present, followed by a festively violent round of musical chairs and reindeer ice cream at lunch, the course of the last day of the autumn term was the same every year. Then, back at home and revelling in the luxury of a half day at school, I’d slot in my old video cassette of Miracle on 34th Street. Set in Macy’s department store, you’d be forgiven for assuming that the film would be soullessly, depressingly commercial.
