RE: The unreported threats to Willow, and Sarah's Wild Story!
This 'story' of Sarah's is typical in many ways but the real clue to her lack of moral core, is that she tells these lies without ANY thought to the natural follow through!
Her WILD RIDE story which she meant to show her to be a tough, mavericky woman ended up making her look reckless for herself and her baby AS well as dismissive of the rights of her fellow passengers.
The Threats to Willow story, which was meant to show her and her family as constangly attacked by 'others' who wish her harm, instead makes her look like a negligent parent, AS WELL as unconcerned for the safety of any OTHER students there.
Lies have consequences, Sarah .... you may have been untouchable in Wasilla, where everyone either accepted your personality quirks, or was too in awe to question you much ..... BUT in the wider world, your fading charm isn't going to trump your lack of character.
