My mother's favourite comment on her aspirational sister-in-law was 'I knew 'er when she 'ad nowt!.
It wasn't until I was an adult and reading an Enid Blyton story about The Famous Five to my gc that I realised that I had always seen myself as one of them, but of course I would really have been the cook's daughter! Like the racism in John Buchan, we simply accepted that that was the way things were. I loved Just William books, and was not at all put out by the Browns having a cook, maid and gardener. Now, there is nothing to stop anybody joining a library, if there is still one left, which has books, in their area, and gaining all the knowledge they need. It won't give them a posh accent or get them a professional career, but it will give them a lot of enjoyment. I got most of my knowedge of history, geography, politics, literature and poetry from reading, not at school.
Fortunately, most of my gc are readers although they tend to read fantasy novels, such as Discworld by Terry Pratchett. I have given up trying to get some of them to read my own favourites - Austen,Eliot, Hardy and Trollope. They say the archaic words put them off. Perhaps they will come round when they are much older.
