Knowledge

Isabella borrowed a 'general history' book from the library the other day and last night we were having a look at it.  We came to the page about the Great Wall of China and she said to me 'I know all about the big wall of China'.  'Really', I said, 'what can you tell me about it?'  'Well, it's in China.  And it's big'.  Oh, and it's made of China'.  (I would say that the last bit about it being made of China, she said half jokingly, she wasn't entirely sure about that.)
