We started the Dec 24 thing years ago when my "switching buddy" passed away. I'd work all Thanksgivings, she'd work all Christmases and since we were both PT we also split our weekend-her Saturday, me Sunday.
Anyway one year I pulled Christmas to work....the kids were in their preteen ages maybe 9 and 11.....anyway we did the Eve thing....it was awesome...no worrying about missing Church, no hurry up and get over to Grandma's for 1200 dinner, plus we could shop if needs be or go to a movie.
Then on Christmas, Daddy and the kids did the Grandma thing. I went to work...usually to a sloooooow floor after all patients don't want elective surgery over a holiday.
We all brought a covered dish to work and the interns and residents joined us for Christmas day. Most of those boys and girls were hundreds if not thousands of miles away from home....it felt really good. Hey I'm 60 to me a 22yo surgical resident can be a "girl" if I want to
Even to this day my kids tell people that where they come from Christmas is at least a 2 day celebration. It worked.
