And I also look after their library. I store all the books that they borrow from their school or friends in my brain．Of course my brain is as large as a mountain, so work like that is no trouble to me．I really eat books just like people eat food． The Lis have a child who is very spoiled. He needs me to remember all?his school textbooks so that I can do?his homework for him．He just gives me the
information on the subject, what has to be done
and the page numbers and I get on with it while?
he?enjoys himself?with his friends．Sometimes

these days．The child has too much homework to do.
