I agree with the reason that communication can change the social of human's relationship.
, Firstly, The communication can make people in society to develop relationships such as if you interested with someone you can develop your relationship by use LINE, MESSAGES, KAKAO TALK. And if you falling in love someone, you can follow him or her by communication in social network such as INSTARGRAM,TUMBLR,SANP CHAT.
Secondly, The communication can make people in the society have become closer such as if you live from different place with your parents.you can communicate by FACETIME,SKYPE,etc. So you can communicate with other people that live far away like video conference .
Thirdly, The communication can make people exchange the opinion for another people more as creating blog for share the knowledge and principle for show the opinion from around the world like pantip.
