Do you really need to say, " Hello" to the world?

It's so easy to program "Hello, World" on C language but it takes courage to say, "Hello" to the world in the fear that what if you become a open blue sky, hanging above without any roof. Will world listen to your Hello? Or it's just you there waving your hands with closed eyes that may be someone do it back to you. What if someone do it? Will you going to handle you soft feelings to his heart? But then don't ask if will it carry in the same way, like you use to do or what if it is just rough careless heart. What if that heart start to validate your inner waves but you just wanted to be invalidate yourself. What if they ask back , '' What is wrong with you?" rather than '' How are you?" Will you answer bravely, " You are good, Okay!" or just leave it without getting any marks on that question and fail in the exam that you took years to lift your hand. 

Do you really need to say, " Hello" to the world? or act as hyper - independence, the one, you never be.
