If she is telling the truth - and I honestly believe she is - then I would do exactly the same in her place. I thought she was taking a child from his family, but he was never visited, had had malaria and TB and had pneumonia when she saw him. She's wanted another child for five years and been planning to adopt for two. I think he will be very loved.
I have often wanted to take home one of the poor beautiful children you see in orphanages, to the point that I cannot watch footage of them on Children in Need or on the news. Just makes me cry. If I had money and influence and could do it, I would.
Now, if she would take all the Kaballah crap out of her plans for the Malawian orphanage she would go up even higher in my estimation.
