It won't be my "first Christmas", but it is the first since the Ex Mrs. Tirebiter said "Adios, I hired a lawyer!".
All my old decorations are long gone, so I'm starting over from scratch. My budget isn't big, and I'll be a household of one, so I'm planning on modest outdoor decorations--lights on the house and the big evergreen tree out front. Probably no indoor tree this year, that will wait till next time. I will send Christmas cards, I already bought those. Several distant friends from the old days will be pleasantly surprised to get one from me again after all these years.
I'm still considering what to do for my kids, who remain very much part of the Organization. I don't want to insult them, but I certainly won't ignore them either. It's a Catch-22: if I get them presents then I'm participating in a pagan Christian holiday, but if I don't then "He doesn't really love you!". I was thinking of one nice keepsake gift for each, and maybe an afternoon of ice skating.
As for what you should do, Excito: what you do doesn't matter nearly as much as doing it with your partner. Talk it over with your wife, plan it together, do it together, and begin your own family traditions. Better seven years late than never! You'll be building on those memories for years to come. Be sure to help her with the Christmas dinner for you and your guests, especially the big clean-up afterwards. Finally, while being Mrs. Excito's partner in your first real Christmas together is a wonderful present for her, do be sure to get her something nice to go with it. Good luck to you both!
