Dear Eric, I am the oldest of four sisters: Ann, Bea, Claire, and Dina. One of my sisters has a history of lying and manipulating others since early childhood.
Despite her unpleasant behavior, she can be pleasant in small doses. However, she often snaps and becomes mean or underhanded without warning, making interactions with her exhausting.
We don't call her out on anything she does, as it's not worth it when we know she'll just lie about it.
A few months ago, Bea accidentally admitted to a years-old lie, revealing the truth.
