A few die-hards will keep their lights up until January 6th : Epiphany in the Western calendar; Christmas in the Eastern Orthodox Calendar.
I was brought up in the "put-the-lights-up-early" tradition-which calls for clearing away all Christmas trimmings by New Years eve. (This made sense, since we used to cut down and decorate our tree-which was precariously balanced in a bucket of coal-within hours of school being let out for the Christmas holidays,and , by New Year's eve,that tree was shedding needles faster than you could sweep them up.)
My late wife was of the die-hard persuasion,and considered putting the house back into civilian clothes before Epiphany to be something just not done in civilized circles !
I imagine I'll split the difference.
I didn't do that much decorating to start with,and I'll probably leave the little potted tree up-and-lighted for a while longer, so that people passing by can see there is still a little bit of Christmas glowing - somewhere.
It will remind me of watching my great grandson on Christmas eve,as he carefully sprinkled oatmeal-mixed-with-sparklers onto his lawn "so the reindeer can find their way to our new house."
It will remind me of what I felt -just after midnight yesterday-when the congregation around me knelt in the darkened church, holding lighted candles,and singing the sweet and simple words of "Silent Night".
It will remind me of being with my family yesterday: exchanging greetings and gifts,and sharing a meal and pleasant conversation with those I love.
Finally, it will remind me of two women : one who can no longer be with me,and one who has become very special* to me - something I had thought would never again be possible.
God bless us all on this day after Christmas !
* I should add, it is very doubtful this special woman will ever be more than a very good friend. I know that is all she's ready for;still : it is nice to dream !
