    Sam wants to borrow a book from the school library.

    He comes to the library with Laura. They can't see any assistants in it, but only a robot standing there. Then Sam says to the robot, "Hey, give me the book." But the robot doesn't move.

     "What's wrong?" he asks Laura. Then Laura tells him, "You must say ‘please' first when you want to borrow something from him." So Sam says, "Please give the book to me, Mr Robot." The robot brings the book. But this time Sam can't take the book out of the robot's hand. Laura tells him again, "You must say ‘thank you' before you take the book." So Sam says, "Oh, thank you very much, Mr Robot."

    The robot smiles and gives the book to him.
