The door to Princess Luna's bedchamber was silently eased open.  "Lulu?" Celestia's voice whispered, as she poked her head into the room to check on her sister, as she had done every day since her little sister's return.  When the sound of light snoring reached her ears, Celestia smiled and began to back out of the room.  But suddenly, she thought she heard another snore, out of sync with Luna's breathing.  

Curiosity piqued, Celestia entered the bedchamber fully, and made her way toward her sister's bed with the stealth of a shadow.  Reaching Luna's bedside, she regarded the scene before her with a fond smile- there was her little sister, slumbering peacefully beneath a blanket, while Derpy lay beside her, a gray wing draped lovingly across her marefriend's back.  

Celestia put a hoof to her chest with a silent 'Aww'.  It warmed her heart to see that her little sister had somepony that loved her like Derpy. Of course Celestia loved Luna, as much as (if not more than) any pony that loved their sibling.  But what had been missing was a romantic interest, and Celestia was overjoyed that Luna had found somepony special.

Turning around, Celestia started to leave her sister's chambers, but something wasn't quite right.  She returned to the bedside and stood in silent observation, before she spotted what needed to be remedied.  Lighting her horn, she very gently lifted Derpy off the bed and floated the covers back.  With dexterity only achieved through many, many years of practice, she carefully maneuvered the gray pegasus under the blanket, back to her rightful place at her marefriend's side.  Celestia gazed at her work with a touch of pride, before leaning down and gently kissing the top of Luna's head.  "Pleasant dreams, little sister," she whispered.  She then gently nuzzled Derpy with a hushed "Thank you, my little pony."

Backing out into the hallway, Celestia eased the chamber door shut with nary a sound.  Continuing on her way, a smile on her face, she began to consider the idea of taking a nap herself.  It was a gorgeous day and her schedule was clean.  Even if my schedule wasn't immaculate, she thought, I'm Princess Celestia, Lady of the Sun.  I think I may have earned one lazy afternoon.   With that revelation, Celestia picked up a little more pep in her step, only to slow down again as her thoughts flashed back to Luna and Derpy.  However, it would be nice to have the company of a special somepony... she mentally sighed, when she suddenly ground to a halt.  She had an idea.  A brilliant idea.  Princess Celestia had a wonderful, brilliant idea.  

Smiling a devilish (some ponies may even say Grinch-y, whatever that meant) smile, Celestia lit her horn and called forth a scroll and quill.  The smile never left her face as she began her letter, My dear Twilight Sparkle...
