Just think and find honest answers of these questions :
How many friends we have with whom we can really share our feelings ?
With the advancing age numbers of our friends are increasing or decreasing?
Do people feel that we are out of reach for them to meet or say something?
Do we too feel lonely all the time?
If the answers are affirmative of these questions than we must be sure about the fact that we have lost our simplicity and due to this suffering to a lot.
