Dear Eric: I have a sister “Carol” who is also my best friend. Her daughter (my niece) is a complete narcissist and also a con artist. Six months ago, my niece’s husband ended up in the hospital with an aortic abruption. After several surgeries, the doctors said he needed a heart transplant and six weeks ago he got a new heart. He is still not doing well. A GoFundMe was started for the family, and instead of using it to pay her bills, my niece uses it to party away.
