What is there about fire that's so lovely? No matter what age we are, what draws us to it? It's perpetual motion; the thing man wanted to invent but never did. Or almost perpetual motion. If you let it go on, it'd burn our lifetimes out.
What is fire? It's a mystery. Scientists give us gobbledegook about friction and molecules. But they don't really know. Its real beauty is that it destroys responsibility and consequences. A problem gets too burdensome, then into the furnace with it.
