Did anyone think the way Mrs Watts described the girls was slightly unusual? She was focused on their temperament, which could also be seen as their behaviour.. Eg one calm, one a firecracker.
I wouldn't normally think much of it but with everything else such as the lack of emotion etc its missing details. Who were the girls? What did they like? What were the into doing? People are more than their temperament. IMO maybe she doesn't really know them and I wonder how well she tried to get to know them.
As for CW, he stood on his porch when his kids were missing and asked to describe them. A gain same thing.. Temperament. If my kids were missing, I would be giving info that would help locate them.. Eg clothing, height, looks, interests as well as temperament.
JMO and maybe in over analyzing it
