Our 12 year old son hasn't had any history of fascination with fire, playing with fire, etc. Nevertheless, he recently lit a fire in the yard. When he saw that it worked, he stamped out the fire and tried to dispose of the evidence by throwing it over the fence. Unfortunately, it wasn't out, and there was some minor damage to a neighbor's shed.
The natural consequences are that he'll have to pay for the damage, and is also likely to have to deal with the police. But this all grew out of two things:
1) He was bored, and
2) He was disobedient. He knows he's not allowed to "play" with fire.
The question is, how do we connect our own consequences to what he did? More to the point, how do you have consequences for something you DON'T want a child to do. It's easy to say, "No electronics until you clean up your room for three days in a row." But you can't say, "No more electronics until you don't set another fire for three days."
