The O.P was an excellent Post from the estimable David Jay, I wonder if he is still about ? I really valued this one, and his many others, which gave me an insight on to the great Jewish views on a number of things.
We always celebrated Christmas when we were J.W's , if anyone had challenged us, we would have said it was a Family Gathering, which it was, about 15 around the table on both days. We didn't then have a Christmas Tree or anything.
In recent years we have given presents, had a Tree, etc.
We are all, as an extended family, non-theists, so nothing religious as such goes on, but we thoroughly enjoy this Happy Time of being with family and friends, the Christmastide always excited me, and it has got better !
This year there will be little of Chanukah in our celebrations, maybe a bloody great Menorah ?
Have a GREAT time at Christmas everyone, whatever your beliefs.
