When I first saw the clip that was posted on our class blog, my reaction was that I seriously would not know what I would do if that happened to me. I guess it also depends on the mood that you may be in. If the teacher broke the cell phone, he would obviously have to pay for it. I can understand how a teacher feels to be interupted during a lecture. It is rude to begin with and it distracts the class. Students should take their teachers into consideration as well. Therefore, put your phone on silent not vibrate, because when the phone vibrates it makes as much noise as when it rings; so what is the point. Enough said, put your phones on silent, it is not that hard.
