I’ve always been ambivalent about Christmas. Because my parents were’t very good at celebrations, my childhood experience of the festival was often one of disappointment. When I met Sue, my late wife, I had to change my views because she really loved Christmas and took great delight in every part of it, and our children learned that from her. But I remain acutely aware of the stresses it puts on people who are poor, unhappy or depressed, when the contrast between their own conditions and the glitzy, showy, consumer-driven atmosphere all around is painful. So it was sweet to find this message on one of the main pedestrian bridges across the Cam this Christmas.
