Is it kind of bittersweet, or are you and your dh enjoying doing it just the 2 of you? Are you decorating much the same as when the girls helped, or doing something different this year?
My kids were never much help with the decorating, they didn't really like to do it, even the tree. They've both been off in their own places for about 5 years but I don't think they decorate much there either, except for a small Xmas tree. This year I doubt that either will decorate their apartment at all because both are coming home about a week before Christmas and staying until after New Years.

I can't recall which year we began the decorating without dd who is the youngest, the last to leave the house and just about the only one in the family that actually enjoyed decorating the tree, or having a hand in putting up any other decorations.
