Exactly this. It makes sense but no sense. They are (or were) "professional parents" in terms of fostering where they're highly regarded amongst the national body. They are also upstanding, vocal and active pillars of their community who appear to strive towards fundraising for various charities and added to this, committed members of their church so how does this all fit? Do they sound like the sort of people that would turn away a needy stranger let alone their own child and grandchild? No. Not to me it doesn't and surely this has had an impact in their own reputations? I'm not saying big Dave should tip off the tabloids but they are condoning this behaviour by allowing her to continue on this path of self-destruction and on towards to the point of actual harm. It won't just be Jack that the predictable downfall will ruin, sadly there are many caught up in this sad web of lies.I think I understand a bit why they don’t say anything. They love her and it’s a terrible thing to out your child as a liar and a grifter. Her career would be over, she’d be a pariah amongst the same people who applaud her So enthusiastically.
I couldn’t do it to my child no matter how angry I was with her but I guarantee her siblings long to do it and just might if she ever, in their eyes, goes too far.
