I don't think he couldn't buy them a home. She said it was a gift. Some parents are just like that
I still don't get why she bought them a fully furnished house, even if they were renting they must have had some furniture and seeing Pandora's style, I'm betting she had nice stuff.
Even if someone gave me a furnished house I'd want my own stuff in it that I've acquired over the years.
Still a lovely gesture from her parents none the less, lucky girl!
