It is usual to speak in a playfully apologetic tone about one's adult enjoyment of what are called 'children's books.' I think the convention a silly one. No book is really worth reading at the age of ten which is not equally (and often far more) worth reading at the age of fifty-except, of course, books of information. The only imaginative works we ought to grow out of are those which it would have been better not to have read at all. A mature palate will probably not much care for crème de menthe: but it ought still to enjoy bread and butter and honey.
