“If you don’t want to answer, ask a question. Don’t use two words if one is enough. Sometimes people laugh. And sometimes they make fun of you. You can and should hug your mother, but you should never hug a cashier at a video store.” These are the rules that Katherine made up for her younger brother David. Without them, he completely goes crazy. “Amazing!” “Why not?” “Disgusting!” “Of course!” “I don’t care!” And these are cards with words that Katherine drew for her friend Jason. With their help he communicates with other people. In fact, it’s not easy for Katherine: after all, the world is slowly turning upside down when you are 12 years old. The book was awarded a record number of literary awards, in particular the John Newbery Medal - an American annual literary award for outstanding contributions to the development of literature for children.
