Pop quiz time.

This one's TRUE/FALSE, and gets all philosophical on your ass.

Context*: A virtual stranger asks you a "Yes" or "No" question, the answer to which is none of his or her business. If you answer "yes," you have rewarded nosiness. If you answer "None of your business," you point him or her toward "Yes." "No" is untrue.

TRUE OR FALSE: It's not a lie if the truth is none of their business.

* -Incidentally, this one is technically hypothetical. I did have a similar encounter, but I have a loophole that lies in the phrasing of the question.
