One winter morning heavy snow was falling and as I headed to the station I stopped dead, alone in the street with the cathedral and just drinking in the sight of a building I had seen a hundred times before. When I got into London a friend could see I was just beaming still, radiating far too much joy for such a time of the week. He asked how I was and I remember simply saying, ‘This morning I saw Notre Dame in the snow’. It was like that.
