Loneliness
There is loneliness in every human being. No matter how happy a human being is in life. In the darkness of the night he feels alone with himself. If you don't get close to a person, you will never understand how lonely that person is! People never want to express their personal troubles! Everyone tries to be good by keeping it inside themselves, pretending to be good! Some people don't know what he is doing. He feels calm when he is restless. People mean loneliness. As we are all alone at the end of the day, we are alone at the beginning of the day! I just cover it with a dirty smile, that's the difference! In fact, we are lonely in the crowd! No one can feel the silence of that loneliness !!
It's true. If you have loneliness , you can't happy in you'r life.
