Done if the most respectable people in this world are straight shooters and tell it like it is. I have always told people, if they want a straight answer without fluff, they can always come to me. You don't do justice beating around the bush. Just say, "Since you asked, the answer ia "yes"". That person can't blame you for being blunt if it's a straight closed-end question. You were just to simply answer with a "yes" or "no" answer. If that person didn't want a straight answer, the question would've been an open-end question, leaving you to explain. Just give what was asked and you'll be far more respected for it. A person that is not ready for the worst answer shouldn't be asking at all.
