The next day after getting back from their rafting trip, Pinkie goes over to Twilight's and apologizes. Twilight gladly lets her friend in and lets her explain herself.
"I'm so sorry for accidentally throwing your book in with the twins' stuff," says Pinkie, a frown on her face. "It was an accident."
"I know," replies Twilight, "Mrs. and Mr. Cake told me."
"I'm just glad you're not mad at me," replies Pinkie.
"Pinkie, I could never get mad at you, you know that," replies Twilight, "now how about you go grab Rainbow and Applejack and we can go out for lunch and you three can tell me about your rafting trip." Pinkie nods and goes off and gets Rainbow and Applejack. An hour later, they meet up with Twilight at the Hayburger and tell her everything about their rafting trip. Twilight listens with a smile on her face. Everything is perfect now and she'd honestly have it no other way. She continues to listen to her friends' story for hours on end. After they finish their burgers, the friends go off to the fair grounds and ride the rides and enjoy ice cream. Twilight is glad they're back and she can definitely agree she'd rather be hanging out with them instead of freaking out over a book like the last two days. That is one fact that will never ever change.
