If there is a fire it must be bothered. It must be prodded several times and sticks need adding to it. The fire cannot be trusted not take care of itself.
This mostly applies to other people's fires. My fires mostly collapse in on themselves gracefully and I might take offense at anyone prodding it before it's ready.
Its just fun to poke at a fire with a stick, but we've had "dont play with fire!" Drilled into us so hard we have to pretend like we're doing something productive.
Weeeelllllll, I’m going to go out on a limb here and state that I do believe my fire tending helps the wood burn cleanly and wholly. That’s why I constantly prod and adjust it.
