Princess Rarity had everything planned for her beloved bodyguard's birthday. It would start with a lovely trip to Trottingham, continue into an entire day in Equestria's oldest library, and culminate into a wonderfully romantic moment in the Ethereal Gardens. It would be Twilight's best birthday yet!

...If only things actually went according to plan.
