Here are two Youtube videos that graphically show exactly how a mother with a bad case of NPD (malignant narcissism) operates. These videos are entertaining in a scary and disturbing way, like watching a train wreck.
Pay close attention to what the mother says–she uses every trick in the narcissist’s book of tricks: blame, insults, changing the subject, interrupting, raging, mocking, “talking over”, gaslighting, projecting, invading boundaries, not taking responsibility, showing no empathy, and just about every other “tool” the narcissist uses to get their own way or avoid taking responsibility for their behavior and actions. Notice how childish the overall effect is–the mother sounds like a four year old having a temper tantrum.
The daughter who made the videos is trying hard to get her mother to listen, but her words seem to fall on deaf ears. She might as well be talking to a wall, for all the good it does.
