She's shared the story of when her "boyfriend" brother surprised her at her flat, to cheer people up. Why on earth would you share that again? They are a strange family!
They have to pay her bills and rent. Her family are not struggling for money. They paid for both kids to go to private school, which where I live the cheapest is 6k a term so 18k a year. They are saving by not paying for private education, so that money could easily go to supporting Poppy. They've sent a spoilt little shit into the world.
