iPad gets a rest, but was it in time?

(( Kids are watching Shrek 4. I think they need to watch a new MythBusters episode. ))

Me: "OK, time for iPad to rest."

Arielle: [[leaps to grab the iPad so I can't stop the movie]]

Me: "Arielle, I need to put this away."

Arielle: "But why do you need it?"

Me: "I need it to make sure my children get smart and their brains don't turn to mush, watching movie after movie"

Arielle, emphatically: "Well it's TOO LATE!"
