I hadn't thought of the Christmas Lectures - she's just 6, so last year probably was too young, next year will definitely be old enough, but this year Everything happened (and the Christmas Lectures were one of his things not one of mine before we had children). I'll try her on the first this weekend - she can certainly concentrate for well over an hour (I spent last weekend trying to get any response out of her at all while she was finishing The Lion, the Witch and the Wardrobe. Ears shut down completely while she is reading, And then there is half an hour of questioning on every single detail of the Narnia universe).
