It really depends on the kid. My mom used to "ground" me, which meant I had to stay inside...with my books. And she wouldn't bother me about going to play with my nasty neighbor kids. Heavenly! I looked to get grounded quite a bit.
If she'd taken away my books, that would've killed me!
Now, keeping my brother at home...that worked *really* well on him. He was always out socializing.
With my kids, you take my son's computer priveleges away, and he sure will notice. Especially if, now that he has so much available time, he has to put it to good use helping me out with chores around the house. :devil:
