OMG I don't even know where to start.
Most of the behaviour esp at the beginning (sloshing water out of the bath and lying about it, pulling the cat's tail etc) sounds like normal bad behaviour for a young child. I wouldn't dream of considering it 'disturbed behaviour'.
"Her tactics were bizarre but insidious: walking strangely, staring fixedly, tapping her feet incessantly, dressing completely inappropriately, often with clothes inside out or back to front.
Everything, in short, to make herself the centre of attention. "
I feel so incredibly sorry for this young girl who has had the most appalling start, and is now being made out to be the Devil Incarnate.
The adoptive 'parents' may not have received sufficient support from SS BUT it sounds like they had astonishingly rose-tinted expectations of their adoptive child. They sound like utter wankers, and I have no doubt that they have contributed massively to the girl's currently disturbed personality.
I can't imagine how heartless they must be to then write about it for public consumption. Loathesome twats.
