"The kid left the house. She didn’t just retreat upstairs. Where did she go? How did she get there? Family car?
Some very missing pieces in this story"
Exactly. I even wonder if this story is true, or how much of it. There is nothing from the daughter’s side. There could be a whole lot more to this story. It kind of begs the question of discussing something with so many assumptions and not enough information.
Could have left out something like an attending family member had molested her, and the parents ignored it. There are many reasons that she could have acted this way (if the parent’s version is even true). There is obviously something significant that is being left out of this story.
