Dear Princess Celestia,
This week, my very talented friend Rarity learned that if you try to please everypony, you often times end up pleasing nopony, especially yourself. And I learned this: when somepony offers to do you a favor, like making you a beautiful dress, you shouldn't be overly critical of something generously given to you. In other words, you shouldn't look a gift horse in the mouth.

Princess Celestia lowered the scroll, muttering to herself, "'You shouldn't look a gift horse in the mouth?' What the hell is she talking about?"
