THAT'S NOT THE SAME THING!!!!!
People in theatres: turning a cell phone off is not MAKING IT SILENT it means turning it OFF. The opposite of ON. As in: If I can see the screen on your phone, it is still ON!!!! If I can still hear the music on your laptop, and you are not wearing headphones, the sound is still ON.
Man...why are people just so inconsiderate. This doesn't happen outside of NYC.
