How many times have you seen a postage or parcel, with ‘Confidential’ written over it?
I always wonder how does it serve the purpose. A matter can stay confidential only when it is kept a secret and not exposed. But when you expose something and also tell everyone that it is confidential, then how can it be a secret anymore? Obviously, an eavesdropper would know that the stuff is confidential and try to break loose into it. Think about this, whenever you see some stuff with the the text ‘Confidential’ written over it! 🙂
