One of the golden rules of dealing with narcissists is to not deal with them at all. You can tell them the sky is blue, not only will they tell you you're wrong, they'll tell you why you're wrong. Not only will they tell you you're wrong they'll tell you the sky is hot pink. Not only will they tell you it's hot pink they'll sound very convincing in their arguments and will exploit your weakness to make it look like they are right. Not only will they be "right" but they will get everyone on board with them. Now that you "lost" your argument they will turn around and tell people how stupid you are for trying to convince them that the sky was hot pink. Do you still follow? Worse kind of personality if you ask me.
