Covert narcissistic sisters play the "poor little me" role in their families to wreak havoc with their non-narcissistic brothers and sisters. They start very early telling lies to the parents about their siblings and then playing the innocent role to the hilt. As they grow older they escalate their sabotage, causing great pain to all of their family members. They plot to take boyfriends away from their sisters by telling lies or revealing secrets or making up secrets. They are believable in their lying. Parents often make excuses for them:"Oh, she is shy and dependent; she is not capable of lying and being cruel; give her a chance; she's unsure of herself; you have to be kind to her." As she grows older the CNS becomes even bolder and as the parents age she becomes "indispensable" to them. In secret she gains their total confidence to the point of being in charge of all of their possessions---properties, investments, etc.
When the parents are gone, everything has been left to her-- a pittance or less to the other children. Who's saying "Poor Little Her" now! Covert narcissists can be difficult to detect. Do the research and you will learn to recognize them---They are to "good" to be true. To learn about the NPD in-depth, visit my website:thenarcissistinyourlife.com
