My ex wife and I alternate weeks with custody of our kids. This week is her week.
That said, Christmas morning I will go over to her house so the kids can open their gifts and we can all spend time together as a family. She’s cooking pancakes, eggs, bacon, and sausage for breakfast. I will probably man the trash bag for the wrapping paper pickup. After that we will go on a family hike at a local park. When I get home I plan to hang out by myself.
