Dorky response: Many campers believe their campfire is out when they don't see smoke, and it only feels "warm".
"That won't start a fire," they think.
And they walk away.
The next day a forest fire breaks out, right where they were camping.
Moral: Every fire is different. Some light easily, and burn fast. Others are slow to start, and keep a steady heat. Others smolder for a long time before becoming full-blown conflagrations. So warm your hands by your little flicker. Enjoy its light. Nurture it and feed it fuel if you want it to get bigger.
Now preschool story time is done. Everyone get their blankies out, and lay down. It's nap time.
