I love her too. She's wonderful. Truly wonderful. DD1 luckily is a big HP fan anyway, but I feel I can hold JKR up as a wonderful role model. She worked hard for her success and is utterly brilliant and brave.
She really does use her money for good in so many ways ,not least by actually paying her fair share of taxes. Plus all the free stuff she's been doing during coronavirus to help children (and their parents). She is donating her author royalties from the Ickabog book (when it comes out) to covid-19 charities.
The world would be a much better place if we had more like her.
