My grandmother used to do this about my mother, in front of me as a child.
I had running battles with her over the years as I watched my mother put herself through hell trying to get some recognition that what she had been put through was wrong.
My grandma never conceded,not even on her death bed.

My mother's mental health rapidly deteriorated after that.
She thought she would get the truth one day.

So I say call it like you see it, and protect yourself as soon as possible.
