I've always said that Watership Down is not a book for children. I say: it's a book, and anyone who wants to read it can read it.
Like the pain of a bad wound, the effect of a deep shock takes some while to be felt. When a child is told, for the first time in his life, that a person he has known is dead, although he does not disbelieve it, he may well fail to comprehend it and later ask--perhaps more than once--where the dead person is and when he is coming back.
Our children's children will hear a good story.
How do they find out with the experiments?''...one way they can find out a whole lot is to make an animal ill and then try different ways to make it better until they find one that works.''But isn't that unkind to the animal?''Well, I suppose it is...but I mean, there isn't a dad anywhere who would hesitate, is there, if he knew it was going to make [his child] better? It's changed the whole world during the last hundred years, and that's no exaggeration.
