Haven't met many 15 year olds?
I was a melodramatic PITA at that age, I can remember screeching at my mother that I hated her and was leaving home. She told me that was probably for the best and I should do so now, while I still knew everything.
Seen the thread on Parenting where posters are comparing teenagers and toddlers?
The girls did not want to go, and they were making it as difficult as possible, fair enough. But Australia cannot ignore the law because they don't like it. We just can't, because it is a much bigger issue than what 4 people want.
If the judge believed they were in danger in Italy then the judgment would have been different, of this I am sure, there was no indication of that though so the law was enforced. I agree with the Hague Convention, we signed it, we can't just decide to ignore it because someone is upset.
They are children and they acted like children. Their Mum had the power to make this a much easier ride.
