Main Christmas tree goes up Christmas Eve and is a family activity that starts Christmas proper. Then becomes family film, wine, cheese and merriment. It seems that Christmas is all foreplay and no event these days.
I remember I used to moan at my dad every year, can we get the tree now, can we get the tree now!!!?? He would always say no and make us wait so that when we got it, decorated it and sat back with the lights off and the Christmas lights on, you knew, right then, that Christmas had started.
