But seriously, it's a longish explanation. My niece's mom is 100% of asian decent and was adopted as a child. When my niece got the DNA result back it told her that she had an aunt she did not know about. My niece assumed it was a sister of her mother that would have also been adopted. My niece contacted the newly found aunt and asked her if she was also of asian decent. The aunt said, uh...no, but we've suspected that my brother might have got your mom pregnant. This aunt remembered her mom (by name) coming around the house to be with her brother.

Then my niece had the discussion with her father. All of us in the family, including my niece and her dad, knew that her mother was not the straitest arrow when it came to fidelity, so although it was probably disheartening for her father to hear, it was not completly shocking. My niece was conceived before her parents were married, so it was not an adulterous affair, just an extra guy on the side while her parents were dating. Once mom became pregnant, they decided to get married but her father always assumed she was his.
