Tough love?

My son ran away today.... He didn't want to change his sprinklers, he finally came home after dark. I asked him where he'd gone, "I was just walking around" "well," says I you just go back outside and walk around until those sprinklers are changed and then you can come home." He went and changed his sprinklers!! It's so nice to have him home! 

Sigh.... Is tough love, tough on the kid, or the Mom?
