I feel something, Lulu!
I sense danger may be near.
Luna's prediction wasn't that far off or too surprising; after all, this was Canterlot, and she was an alicorn princess. It was practically assured that she would find trouble, or trouble would find her. I believe there is a set of universal rules that govern our world that specifically applies to alicorns and everpony near them, and it most likely follow as such; one will always hate bananas, one will always hate apples. Alicorns get all the cake, and as a penalty to that, alicorns also have the weirdest misfortunes ever, and the ponies they are close to also suffer from these misfortunes, though on a smaller scale.
Currently, Luna was located within the dining room with Quackum and Blueblood, and all three were in the process of eating a very satisfying lunch. Unfortunately, that might change very soon, as Luna sensed that things may be taking a turn for the worse, which was a pity, as she didn't yet get to eat the wonderful roti tissue dessert that the chefs in the kitchen, for once, made on time for her lunch. It was sitting there, in equal distance to the duck, unicorn, and alicorn, and each had commented on such a fine looking dessert before starting on their main meals, looking forward to when the roti tissue would be eaten. Hopefully, the roti tissue would be spared for later consumption.
"Bluey," Luna spoke, wanting to alert the unicorn in case he did not yet know, "I sense danger. Are you feeling it? Something is going to happen soon..."
With a nod, Blueblood was now casually but very attentively looking around the dining room, sensing the same uncomfortable feeling of danger that Luna did. "I'm feeling something, alright. Should we attempt to defend ourselves?"
With a shrug, Luna continued eating. "Can't really defend yourself when you don't know what the threat is, Bluey."
A quack from Quackum seemed to agree with Luna, and Blueblood nodded slowly, agreeing with Luna's analysis of their current situation, though he did not like the fact that Luna was basically suggesting to just stay put. "Very well, then. I-"
Blueblood's words were interrupted as a loud thud was heard as a pony with a rather comically over-sized duffel-bag filled with mail crashed down in front of them, causing all three present to recoil from the sudden, jarring impact of the pony hitting the table. Thankfully, the roti tissue was spared, and the pony didn't seem hurt from the impact, merely dazed.
With a muted quack, Quackum walked up to Blueblood, and jump up, nesting on his head, though in reality, Quackum was preparing to use Blueblood as a shield to take the full force of whatever danger may be coming her way. Luna smiled at the sight of a slightly annoyed Blueblood with a worried looking duck on his head before inspecting the pony that had crash-landed on the table.
It was a gray pegasus, with a dirty blonde mane and with bubbles as a cutie mark. The most striking feature about her, though, was her eyes; they never seemed to both point in the same direction, which made Luna feel concerned about the health of this pegasus. She got up from her chair, and moved up to pegasus' crash-site, checking over her to ensure that she didn't have a serious injury. "Pray tell, are you alright?"
The pegasus looked over at Luna (causing the alicorn to cringe inwardly when she saw that her eyes still weren't straight), and nodded, giving her a salute. "I'm okay, mam! I'm Ditsy Do, working for the Peg-Ex, stationed in the Ponyville branch, ranked second lieutenant! We push the envelope everyday, all day, delivering letters and packages to those ponies that are expecting one! We only have a twenty-five percent casualty rate of lost and slash or misplaced mail, ten percent lower from our closest competitor, and most of our losses and misplacement of letters and packaging are caused by me! You won't find a better mail service anywhere else in Equestria!"
"...I see." Luna looked over towards Blueblood, who shrugged, clearly as lost as she was. Some help you are, Luna thought in annoyance as she looked back down at Ditsy. "Well, Ditsy, what mail comes from Ponyville?"
"It's from Pinkie Pie, classified as 'party'!" Ditsy reached into her bag and pulled out an extremely festive-looking letter, in pink, with stamped balloons on it and what Luna swore to be sprinkles on the outside, as if it were a cupcake. "She says it's an extra-special letter for you, and extremely vital that you take a look at the letter immediately!"
Extra-special, eh? Luna took another look at the letter before placing a hoof on it, ready to tear the letter open, when Blueblood shook his head rapidly.
"I feel something, Lulu! It feels like something terrible will happen if you open that letter. Don't do it!"
Pfft. It's a letter. I sense no magic or harmful substances located within the letter itself, so, obviously, it must be safe. I'm confident that Peg-Ex screened the mail! "Fear not, Bluey, as an alicorn, I have the power to trump whatever is inside this letter! That, and it's not like you can put much dangerous stuff inside a letter." Without heeding his warning, Luna tore the letter open, unaware of what she just unleashed.
"Surprise! Happy It's-Almost-Your-Birthday! Woo, it's hard, stuffing yourself in an envel-"
While Luna was prepared for a great many things, she was not prepared for a pink pony to pop out from the envelope. So, she did the most rational thing that anypony would do in her situation; fling the envelope away. Unfortunately, she did not give much thought as to where she flung it. She watched as the envelope (plus one Pinkie Pie) sail into the air...And land on the roti tissue.
"Wow! Your throwing hoof is a bit lacking, Princess Luna! I barely flew!" Pinkie Pie chirped as she climbed out of the envelope.
Luna's attention was not on Pinkie Pie, who had somehow defied all known paths of logic when it came to mail, but on the delicious roti tissue dessert that she just ruined. She swore she felt her heart break upon seeing such a wonderfully crafted dessert in utter ruins. "Nooooo! The roti tissue! It's...It's ruuuuuuuuined!" Luna fell down onto the floor, crying and wailing.
Confused, Pinkie Pie looked at where she landed, and saw that her landing site was in fact a now ruined roti tissue. Being a long-time goer at dessert conventions across Equestria, Pinkie Pie's eyes could not take in the dreadful sight. Immediately, she bounded off the table and began crying with Luna, joining a comrade who was also suffering from the same symptoms of dessert destruction. Instinctively, Luna hugged onto the pink party pony like a giant plushie.
While the two were shedding tears over the ruined dessert, Blueblood stared at the two for a moment before turning his gaze over to Ditsy. "Lieutenant?"
Ditsy saluted Blueblood, tilting her head slightly. "Yes, first lieutenant Blueblood?"
Blueblood took a moment to clear his throat before tossing a small bag of bits at Ditsy. "Here's your tip."
"Thank you, sir!"
