Good that she just figured that one out. Everyone should learn it at some point.
When speaking in the first person and referring to one's parents as 'Mom and Dad' 'my' is assumed.
Wow! I guess she was lied to all of her life and just now found this out
oh-kay .... I'm so glad this was clarified. Before I read this, I thought maybe her uncle and aunt were her parents, and her mom and dad were only her friends.
