I've never celebrated Christmas and have been raised as a disciple of Christ. I don't begrudge anyone their right to decide what to or how to believe. We are all created to be free moral agents.
Now all my kids are out of state with no plans of visiting, so for me it's like any other day to which I'm accustomed. I don't plan any special projects, maybe take the time to think about the "to do" list of projects that keeps getting longer and longer. :D :D
