Turn Off Your Cell Phone
With the development of information technology and reduced price of communication products,the mobile phone has become a necessity for most people. Obviously, it shortens the distance between people and makes our life more convenient. Thanks to the cell phone,it's easy for us to contact or be contacted by others anytime and anywhere. We will never miss any important meetings, great deals or admirable opportunities.
However, have you noticed sometimes the cell phone also brings embarrassment to us?It's not rare to see someone pressing the cell phone to his ear and shouting loudly in public as if there were no one else present. And I'm sure each one has had such an experience that the cell phone ring continuously on a formal occasion. Perhaps these people have many life-and-death reasons to keep the phone working at all times, but it interrupts people around them who have to hear what they don't care when they want to concentrate on what they're doing.
So if you are one of them,please shut off your cell phone in public,especially on a quiet and serious occasion. It's a respect for both others and yourself.
