Why can’t do we do not? While on the one hand we can build relationships like mankind has been doing for centuries, on the other hand we can facilitate this process thanks to social network. I personally find social media very useful when it comes down to maintaining contact with people we met abroad. Thanks to such tool we can stay updated on our friends’ lives and be part of it. Therefore I think that by combining both we are able to create long-term, strong relationships. :)
