I was 5 when I decided to enhance a 1902 copy of Clara in Blunderland by colouring and writing in it. It was a spontaneous act of anarchy (fittingly the book is political satire). I didn't like the look of Clara. She had narrow temples and bad hair, so I scribbled on her.
Then my instincts were bludgeoned into submission by 'don'ts'. From adolescence these were replaced by 'do's'. Do be a consumer. Conform.
Reader, I shook it off. Children and the best children's books are anarchic. Like.
