When there were no mobiles, perhaps the fear was less.When I was young and used to go outside the house to any friend's house, I never felt that my mother or family worried about me in any way. My father or other members used to go on the journey even the elders of the house used to believe that their journey would be good, while there was no medium to talk during the journey.
After the advent of mobile, we have become used to calling our loved ones again and again, especially when they are traveling or out of the house. And if the person in front does not pick up the call, then different types of illusions and thoughts start coming into our minds. Agreed that mobile is a big revolution which has also helped the people but somewhere in the mind a confused situation has been created.
