"The Oath against lying does leave room for sarcasm. It is intent and result that matter. No sister can intentionally speak an untruth either with the intent of passing on false information or with the belief that false information might be passed on. Thus the careful slicing and dicing of words. But if someone were to hold up a piece of white cloth and ask whether it was black or white, someone who had sworn the Three Oaths would be capable of saying that it was black as a matter of sarcasm. But not if, for example, the person asking the question was blind and thus might well take the statement for truth rather than sarcasm."
