Lights out!

Almost daily the students beg, " Can we turn the lights out? It's so soothing and relaxing." I say, "so relaxing you fall asleep."
They assure me, "No we work BETTER with the lights off."

Guess what happened today? Power outage!! No lights. Now, what are they saying? Yep, "Awe there's NO WAY we can work with the lights off." Yeah right.
