Well, it's only 3 years until the end of the world, so let's take stock of where we are: World. Hell. Handbasket.
What's happened to Christmas? It's the celebration of the birth of Christ, but we've turned it into a bacchanalian festivus of commercialism and nonsense. It's turned into something that's all about us, and not...everyone else. Have we become so self-centered that we've lost our ability to care for anyone else?
This Christmas, try something new, and do something selfless. Think about someone else. Then consider that the gift of Christmas is about that, only magnified beyond your human comprehension. Yes, you're smart and wise. But you're a mere speck in this universe, and you need to consider that you might not be the center of it.
If you can't be thankful, at least say thank you to someone. We're better than what it appears we've become.
