E's favorite book

E's favorite book right now is the book David Gets In Trouble. He absolutely loves this book. We have to read it every night and HE has to read it. He doesn't want you to read it. Since reading this book he has picked up a few new phrases like "it was an accident" and "I didn't mean to". He says these all the time when we tell him something which usually his reply doesn't make sense to what we have just told him. He just remembers David said them in the book.
