You found the open cookie jar and followed the trail of crumbs toward your son’s room. He looks up innocently enough when you ask if he ate the cookies. What might give you a clue as to if he is lying or not?
Someone who is lying will often cover his or her eyes, nose or mouth with the hand during the conversation. This is called a “negation” and may be a subconscious way. Of course this isn’t complete fact – the dog may have REALLY eaten them!
