"You can't lose Christmas.You STILL can't lose Christmas, Ralphie - Christine Moers
That's it. No details. No exceptions. Period. Finito. That's that.

I have literally said to my children, "You can burn the house down. We will move into a hotel until the house is rebuilt. We will collect insurance money, rebuy gifts and still have Christmas. Because you can't lose Christmas.""
