Human relations are badly damaging with mobile phones because people are not meeting one anorher and at least not comignto functions simply sending the sms greetings which badly disturbed relations.  Earlier days people coming to the homes of their friends and relatives  and such effection is not there now a days simply calling them through phone which is incorrect.  Man is a social animal he has to live in the society with personal contacts but not mobilecontacts.
