Cell Phones, again

I'm in agreement with the writer of this op-ed in The New York Times.

Here's my response:
The writer gets a perfect score, 100% from me. I'm a teacher in Israel, and a high percentage of my students' attention span is wasted on the phone. I insist that they turn them off.

"It's on vibrate," they reassure me.

"I said OFF!" I repeat. "If I could turn mine off when my two sons were in the army, you can turn yours off!!"It's an international problem.
