I love the opening lines of this story - the rhymes throughout, like a song -and the sense of child who sees one thing but is told by a parent that no, you're mistaken, your mom says it's not real and it's all in your head. Classic trick of an abusive parent.

And I love this! the stupid cow of a niece

No wonder Mom is unable to defend her daughter - Mom is herself a victim - but it sounds like she was a bad mother even before that.

Awesome ending! Did the good little girl give up and go to the dark side herself?
