FACEBOOK as every one knows is one of the famous and mostly used social networking site. Each and every one uses it for chatting with people. Fb users can also post images, texts, can check in etc. They can share their views. But it too kills face to face communication. When we have a face to face communication a person can express his views properly with a facial expression. While talking the opposite person can see our facial expression and can react to it. But chatting on Fb, not only Fb but every social networking site kills this expression , the person with whom we chat can't understand our expressions while sending the message. Misunderstandings may take place. This is how it kills face to face expressions or communication.
