Friendship is Dragons

GM: Since we've been building up to it in our main game, how about we do a trial run of the Gala for tonight?
Insert: Two Hours Later
GM: So...what have we all learned tonight?
Bonnie: Pardon me?
Rainbow Dash: It's a roleplay thing we do, we 'write' a letter to the Princess about whatever lesson we learned

during the game on Friendship. I guess I can start us off.
Rainbow Dash: Dear Princess Celestia...I shouldn't try and melee an ooze.
Twilight Sparkle: I shouldn't have let Bonnie temporarily turn me into an Alicorn. We were useless.
GM: And?
Twilight Sparkle: And if I hadn't said she was going to be useless, she might not have.
Bonnie: Dear 'me', I shouldn't play a princess. Or render my party members 'useless'.
Rarity: I should have played Luna.
Applejack: Uh...I should have eaten before I left? Sorry, Applejack really didn't do anything wrong.
Marceline: I shouldn't have let that chimera dude walk my pet Ooze.
Fluttershy: We should have realized witha name like Discord.
Pinkie Pie: I have no regerts!
Marceline: Don't you mean regrets?
Pinkie Pie: Nope! What about you, Phoebe?
Phoebe: I should have had an afro.
Pinkie Pie: I like that one! Can we keep her?
