Good points, Magna-Carta. It's becoming harder and harder to know what to believe.
Which reminds me that anything written on social media is subject to questioning and skepticism. Even stories that are absolutely true should be viewed with a skeptical eye. After all, these are not news articles, which have been vetted, edited, and there is something really at stake if they contain any untruths masquerading as fact. In these conversations, anyone can say anything, as long as they adhere to the rules of the forum.
In human relations, trust is so important. And that doesn't necessarily mean anyone is deliberately lying. Sometimes people are completely convinced that something is true, even if it isn't.
Which brings me to one question I have. I agree with you that the "several hours of knocking and scratching" raises a definite red flag. I can't think of too many things that would be more terrifying than that. It took her a few hours to call the police? And if she's going to say she called them right away, it took them hours to get there? Something sounds a bit "off."
