Sherri accuses her mom, Betty, of lying to her throughout her life about the identity of her biological father. Sherri says she was led to believe the man who raised her was her father, but 16 years ago, she says she received a letter from an 11-year-old girl who said that she and Sherri were sisters and that their father was a man named Wayne. Sherri says she questioned her mother who denied the claim and refuses to discuss the matter. She maintains that to this day, her mom will not admit that Wayne is her father or that she had been in contact with Wayne during her childhood.
