Tidyskatemum I feel rather like you do. Not that many years ago Christmas Eve and Day were the start of the festive season, not the end.
For us, it signalled the start of a few days holiday and we would spend time between Xmas/NY visiting or hosting friends and family for afternoon tea (leftovers, of course!) and so on.
As a family, we try to keep that tradition going but it's difficult in the face of people wanting to rush back to the shops on Boxing Day and ripping down decorations.
One year, my son and family who live in America came over for Xmas on 23rd Dec. When we took the children into town, the shops were taking down their decorations, replacing them with sale posters and cut price goods which people had paid full-price for just a day or two previously. It looked so shabby.
I acatually complained to one department store, one that is never knowingly undersold, and they did have the grace to look a bit shamefaced.
