When my children were little, I did the whole Christmas thing - decorating, tree, presents, plenty of food etc.
I’m 70 now. I live on my own. I don’t do trees, decorations etc at my home. My children understand and respect that and they know the reasons why as do my older grandchildren.They all chip in for food for Christmas Day and we have a meal together. They buy me presents because they want to because they do Christmas because they have families. As a religious festival, it has no meaning for me whatsoever.
