Nowadays, there is growig concern about the lack of commuicationbetween adolecents and thesenior. As is often the case, teenagers find it more comfortable to share their feelings with their classmates instead of parents or teachers. so important is the communication between generations that the absence of it will surely lead to a diverse variety of problems. for ne thing, the growing misunderstandings turn out to be the direct consequence of commmunication decrease. For another, failure in effectiv communication keeps teenagers from turning to their parents or teachers for advice and aid. In my perspective, the reaon are better worth reflecting on than phenomenon itself. there is no denying that the increasing popularity of social network is to blame for weakening teeanagers' capability of expressing their feelings to others in person.Anyway, appropriate use of online communication is called for to settle the problem.
