Rainbow Dash saw her friends they said, "Surprise!" Pinkie Pie's cannon.
Twilight said, "Hi, Rainbow Dash we are just here to celebrate what wonderful gifts you gave us and we are here to say thank you for the gifts.”
"Thank you for the gifts, Rainbow Dash!" Everypony said.
"You're welcome guys,” Rainbow Dash said, with a big smile on her face.
"So does everypony want to say thank you to Rainbow Dash? I'll go first Rainbow Dash thank you for the book you gave me,” Twilight said.
"You're welcome,” Rainbow Dash said.
"Thank you for the poster y'all,” Applejack said.
"You're welcome,” Rainbow Dash said.
"Thank you for the cupcakes I ate it all hehe,” Pinkie Pie said.
"You're welcome,” Rainbow Dash said.
"Thank you, Rainbow Dash for the lamp,” Fluttershy said.
"You're welcome,” Rainbow Dash said.
"Thank you darling, for the outfit,” Rarity said.
"You're welcome,” Rainbow Dash said.
"You all taught us a lesson to thank our friends Rainbow Dash,” Twilight said.
"And I have taught myself a lesson to always love you're friends,” Rainbow Dash said, and the main 6 had a group hug.
I like the concept of this story, but...
1: They already said “thank you” before when they gor something.
2: Princess Celestia would never turn someone into a princess for giving gifts, like I said before: Rarity would have been one at least.
I'm sorry, but this is just my honest opinion. I'm going to read the rest now.
