Sparks

You know how it only takes a spark to get the fire burning?

If the flame warms people up and make them comfy, cooks the food and provide light, it's good.

But if the fire burns down the house, takes away life, and destroy other houses in the process, it's bad.

Watch out for the sparks you set off in people. You'd just never know what it will turn into.

It might even end up burning you.
