Fascinating , thanks. And in terms of quotes catching one's eye, the one that struck me was
Nellie didn’t like her quiet, polite child having to mix it up with kids “from all walks of life,” as she puts it.
Hmm, yes; this is obviously where I went wrong with my own two children, letting them mix with "kids from all walks of life". Maybe if I had been more discriminating, they might have got proper jobs like high flying education executives with companies like Pearson instead of teaching and supporting underprivileged children in the East End of London.
