One day while Twilight was busy writing a poem, her friends went to Princess Celestia, and told her what happened. Celestia asked "Why did Twilight not trust you anymore? Tell me." Then Sunset said "Well, we invited her at a sleepover at the Golden Oak Library, but we didn't keep our promise." Then all 6 ponies looked down at their hooves, feeling embarrassed. Celestia gave them a tip on how to gain Twilight's trust again. She said '" Ponies, if you want to have her trust again, you should apologise and promise not to do it again." So when Twilight was in her living room, reading a book, her friends rang the doorbell. Twilight shouted "Come in!" and her friends walked in. When Twilight saw them, she said " Oh it's you, what do you guys want?" Then AJ (aka Applejack), in her Texan accent said: "Look Twi, we came to apologize." Then Pinkie said " Yeah, for not keeping our promise." All 6 ponies promised to Twilight that it will not happen again. Twilight forgave them, and the Mane 7 including Spike, had parties and happy days ahead of them.
