Once upon a time, she was a genius with dreams, pursued by everyone, one of the guys, or content in screwing people over. Then you came into the picture, and she hates you for it. You might be a decent kid. A prodigy even. But that doesn't matter to the one that raised you. You stripped her of her goals in life. Whether or not that belief they hold has any factual basis doesn't matter, for your caregiver has become the Resentful Guardian. They may feel love and protection towards the child but they will have one eye on the past and what they could have been. They'll make attempts to get some of that old life back and it will end up with some neglect of the child.
