One of my sisters related a conversation she had with one of her kids:
Emily picks up a book entitled "The Paper Airplane Book" with the cartoon picture of a boy with paper airplane in flight. "This doesn't look interesting, but I'm going to read it because 'you can't judge a book by its cover.'" "It's about making paper airplanes." She looks inside the book. "It's about making paper airplanes? Then I guess you can judge a book by its cover." Shuts the book.
My sister who is home schooling her kids showed me a writing exercise her eldest boy completed last week. The assignment was to write a description of a certain Aesop fable: "The Ass And His Driver". Being an innocent young home schooler, he only knows the word 'ass' to mean 'donkey'. His description of the fable was unintentionally funny, and we laughed over it like immature school girls.
