Discernment is so critical.
Like fire, some naturally die out on their own especially if in a fire pit or other contained area while others might kill and do serious harm left unintended. Perhaps burn the house down or wipe out a whole forest.
Too bad most aren’t like the fire in my gas grill. Knowing the difference is key. Shutting the lid or thowing a wet or fire blanket takes care of most with a quick glance now and then to confirm.
