If parents have a healthy relationship with their children, it'll give a healthy view of life to children, and if parents don't give a significant importance to their relation with children then it'll spoil the children' life unconsciously.
Sometimes parents think that they should keep a distance with their children and should not mix up with them like a friend because it is against their relational dignity. But they are wrong, because they don't analyze the fact that the gap between parents and children creates a negative impact on the child personality.
The children that don't have a good and friendly relation with their parents , can't face the world bravely, can't be so confident as they need, can't be so social as a human being should be and more importantly can't have strong relation with others in their lives.
Sometimes the communication gap between the parents and children affects the children too negatively that they lose their own personality and sometimes indulge in some anti social activities and can become a problem for the whole society as well.
