During the Great Depression, her mother became an alcoholic and sent her to the foster care system due to being unable to raise her anymore. Each foster family was unbelievably abusive towards Mildred and her blood brother as they endured physical beatings and insults for the most trivial of reasons. To top it all off, their final foster family forced them to perform sexual actions onto each other for a crowd of perverts and pedophiles.
