Heh. I just realized it's another border thing - construction and destruction both. You are making the fire, keeping it going steadily, tending it; at the same time you are consuming the fuel, destroying the wood or paper or what-have-you.
I don't have a shredder, but I do have a fireplace. So as part of this move, instead of hauling boxes full of old papers around, I'm doing a little destruction.
