Aha! Clever.
One thing technology has done for us is that we now have an array of "things" to deprive her of if she misbehaves. In my day, it was "go to your room!" Now if she goes to her room she still has all her "stuff".
My parents got around that by sending me to their room.
When my son was younger he was such an avid reader that we could actually get him to do his chores, etc. by threatening to take his book away, LOL.
Yeah, those days have gone, but we find that depriving him of "social activites" seems to be the great motivator.
He's very active in our youth group at church, and plays in a band there a couple nights a week, and when we've had to threaten, we sometimes laugh, because the threat comes out, "Do such and such, or you won't be going to church tonight." Sounds ridiculous, but it works.
