Why do you think Robert liked The Wave so much? Why was he crying at the end?

Robert finds actual meaning under Mr. Ross and his autocratic rules. Robert goes from being a nobody to asomeone with purpose. A fascist state can give everybodty the same meaning in life. All of a sudden Robert finds himself on par woth other students. He becomes more outgoing within the context of Mr. Ross's rules and reall looks a lot more happy. Robert feels lost when the wave concludes.
