Hello! Communication has always been the most important part of our life. We can\'t live without it. So can\'t teenagers. Remember yourself when you were young. You had to chat with friends and classmates. Now it\'s not a problem, because there are a lot of social networks and different ways to say \"hello\". Of course, teenagers prefer virtual chatting nowadays. It\'s quick and easy. You just need to tap some buttons and voila - your friend receives a big letter. A lot of adults think, that it\'s the wrong way to keep in touch. It\'s simulated. But I think, it\'s one of the best attainment of progress. Our life becomes more and more dynamic each year, so we have to be in time. It,s great to improve ways of communications.
