Friendship is work. Friendship is a feat. Friendship is pain. Friendship is not an iced cake that you can eat while happily laughing. Friendship is the greatest test. For friendship you must be able to clench your teeth and swallow blood. You must tolerate friendship even if it brings you pain. Friendship is a war for which victory is not guaranteed. Friendship can be immensely bitter, because of which it is prized. But you... you did not study well, Twilight Sparkle. I think that Princess Celestia needs to think about the future of your studies.
