Others are simply ... well, rituals.
I celebrate the season in all its permutations and I guess it's because I like to prolong the spirit of Christmas. So all my Christmas spirit will continue through tomorrow... even without the visible reminder of a decorated tree ... and my New Year resolution is to try and keep that spirit all through the year.
Resolutions : now is that a ritual or just silly, given how often they are not kept???
Happy Christmastide to you all.
