I have never really liked the tinsel and glitter of christmas and, these days, actually resent the light pollution that comes from so many people thinking that they need to decorate the outside of their homes as well as inside.
When the children were small, and the in the years I had Christmas at my house, with g.children I did decorate, not a lot, but enough to keep them all happy. Always was delighted when I got it all down and put away on New Years Eve. A couple of years back, thinking I was moving to a smaller place I got rid of all the decorations I stored, and have never felt any need to replace them. I am always away at Christmas, and really cannot see the point. I am not a killjoy, enjoy any festive occasion, whatever religion it is supposed to be based on. Do get all my children and g.children Festive Presents. But decorations - no thanks, particularly the lit ones.
