/*
 * The fireplace, and cleaning up.
 *
 * Wood lying in a fireplace is its fuel. Lit, the fire burns it down piece by
 * piece and goes out when nothing is left. The more wood, the bigger the fire,
 * and the more water (or pee) it takes to put it out. Food held close to a burning fire,
 * or lying on its grill, gets done, then darker, then burnt. People like to sit
 * (squat) round a burning fire.
 *
 * Trash goes into a garbage bag held in one hand, a piece at a time; bags and
 * loose trash go into the waste container.
