Narcissists are the most dishonest people you'll ever met. They'll provoke you and verbally attack you. When you react to their abuse and defend yourself, they'll turn either rageful or play the victim in front of others to make you look bad. They are con-artists who are spiteful and vengeful. --jo
People usually talk about their mother-in-law, but it happens with a father-in-law, too. Cringe worthy sentences that begin with "You ought to", "If I were you", "why don't you", "what you need to do", "why don't you", "you should", "why do you do it that way", "What I did..". The list goes on and on, even though advice was not asked for.
