Earlier, before the accessibility of mobiles, people used to meet face to face, exchange feeling and feel happy to have met. they used to write letters if they couldn't meet. People were not too busy and used to have a long chit chat with friends and family. Family relationships were stable and in a good state. now, due to mobiles, people hardly ever meet. they just call each other or send emails.
the joy of meeting an old friend directly is much better than just chatting in facebook and other social media sites.
