Here in UK there is a tradition for companies to try and out do each other for alternate, interesting Christmas ads and John Lewis generally always make the best... But this year Sainsburys has really blown me away. The advert is based on the real event from World War 1 where British and German troops left their trenches on Christmas day after they heard each other singing Christmas carols and genuinely did meet greet and play games together for Christmas, only to go back to fighting on Boxing day.
