It's not hard to identify a person remaining in a cage. But a person remaining in a hidden cage is hard to identify. The cage does not have any physical outlook but it exists like air.
Air that you can't see is not hidden from the world. This is an open secret to everyone. Some people grow up only to go inside this hidden prison. Someone's ultimate target is to remain in that place. Only prisoner knows how he feels within that prison. Some are happy and some are confused to lead a subservient life.
I feel that I am within a cage for some months. Cage that only I can feel.
