For those who have lived in Anglo-Saxon countries, the Christmas period has always been a magical time when the sleigh bells responded to the warm voice of Bing Crosby, Nat King Cole and Frank Sinatra, where Harrods' magic windows and the windows of every toy store in New York were accompanied by the Christmas song of the year and the eternal Jingle Bells and Holy Night in the snowy night. A sweetness envelops these images and a certain nostalgia invades us.
