answer:If your sister did not have her daughter’s permission, it was so inappropriate and offensive that i can hardly stand it. When the little girl (which she surely is) finds out, she will feel furious, embarrassed, betrayed and frustrated. MY mother told her best friend (I was able to hear them chatting in the living room when I was in my bdrm with the door open. I was almost 12, and can still remember my feelings of rage, humiliation and disbelief. i was too afraid to confront my mother. I would wade in with your sister and plead that she take the comment down. Shame on her. Good for you; the daughter, it would seem, needs an auntie advocate.
