Christmas traditions speak of warmth and family togetherness. Our family likes to gather in the living room, where the children, dressed in white, tussle playfully over a giant lump of coal. Then Daddy says how great it is that Mommy can still fit into her wedding dress, and isn’t it about time for the kids to take their coal and go to bed? Yes. Family togetherness and fossil fuels–that’s what Christmas is all about.
