Okay, so hi. I've just finished my Paper Bones Don't Break story and now it's time for me to start writing happy things again! I'm so excited for this story. It's my very first crossover, after I've sworn I'd never write one, but I just felt like I needed to do this for myself. I don't know when I'm going to update next, but I know it will definitely be soon. So please review and let me know what you think! And as always enjoy!

"Elsa Elsa Elsa Elsa Elsa!" Anna screamed out, the name toppling over her lips to get past them to fly out as fast as possible. Anna went bounding down one corridor after another to get to Elsa's study, a letter crinkled and crumpled in her vice like grasp.

Elsa could hear the distant shouting through the walls and a little smile crept onto her face as she set down her book on her desk. She figured her sister was still far away enough to at least have one more sip of tea though and so she brought her little teacup to her mouth and took a nice slow swig from it's steaming contents, and it radiated it's heavenly warmth through her. Then she set the cup back down next to her old ratty book and then pushed herself away from her desk and stood up from her chair and then she went to the door to receive her little sister.

Anna's footsteps were light but thick as they pounded the carpet outside, and they weren't slowing down. Anna had faith that Elsa's door was already open, and lucky for her Elsa had just opened it in the nick of time, but unluckily for Elsa that meant she came toppling down with Anna running her over.

"Elsa! Oh I'm so sorry!" Anna screeched apologetically as she climbed off her fallen sister.

Elsa chortled as she rubbed the back of her head that was smarting from being harshly introduced to the ground. "I'm okay, are you?" Elsa asked with a slight grimace when she pressed a little too hard on the rising bump.

"Yeah, I'm okay! Let me help you!" Anna quickly went to help lift Elsa up and before Elsa realized it she was back on her feet again. Anna's strength still perplexed her after the year they've spent together after spending thirteen apart.

Elsa shook her head out of her reverie and to get rid of the theories of her little sister's strength that swirled in her mind and went to straighten her hair as she began to walk back to her chair behind her desk. "Thank you Anna."

"No problem. Oh! I almost forgot!" Anna lifted up her hand holding the letter and held it out for her sister to see, but Elsa was busy combing through her hair with her fingers and pulling her chair out.

"We've received a letter from the kingdom of Corona! Princess Rapunzel has invited us to her birthday celebration! Isn't this exciting?!" Anna was practically squealing with utter excitement and it was more than enough to make Elsa pause before sitting down. Elsa looked to her sister's hand and at the crumpled parchment held within it, and again she chortled at the mere sight of it all damaged, but still she gestured for Anna to give it to her and Anna bounced over and handed it to her.

Elsa took it and first yanked it at the ends to try and straighten it out again, but the handwriting was still pretty illegible with all the frivolous creases lacing it, but she made it look like she could read it otherwise.

"Exciting indeed." Elsa said with an absentminded tone, as she was truly trying to attempt to decipher what the letter was entailing.

"You don't sound very excited." Anna said a little crestfallen and a blush dusted her freckled cheeks when she felt that she had been making a complete fool of herself to just come barging in with a crumpled up piece of official parchment that she knew no one would be able to read.

"Hmm, what? Oh! No, I am excited! This sounds very exciting! Isn't she the one who gets the lanterns set off for her birthday?" Elsa set the letter down on top of her book and then gestured for Anna to sit down on the couch that she had brought in a year ago for her, in front of her desk. But Anna didn't want to sit down, she simply strode over and sat on the corner of Elsa's desk as Elsa sat down in her chair, and Elsa smirked at her, but Anna payed no mind.

"Of course that's what you'd only remember about her." Anna teased.

"I know she also married a thief." Elsa lightheartedly bantered back.

"She's also the one with the magic hair you big dummy! Why don't you get your head out of these books and get it outside some time! You're missing out on so much!"

"Because, I like my books. Besides I've had it up to here with magic and sorcery. I'm not interested in other's."

"Party pooper." Anna huffed and then she stuck out her tongue to finalize her crude argument.

"Would a party pooper decline a party invitation?" Elsa asked with a cocked brow and a sly smile.

"Wait... So, we're going?!" Anna's eyes lit up fifty times brighter than the sun itself, and when Elsa gave a small nod and a big smile Anna lunged herself forward to tackled her with a walloping hug.

"Thank you! Thank you! Thank youuuuu!" Anna yelled gleefully into her big sister's ear, but that only made Elsa grin even wider at the fact that she was making her little sister very happy, and so she wound her arms around her just as tight.

"There's no need to thank me. I'm sure you would've gone by yourself even if I said no."

"Hmm. Maybe you're not a big dummy after all." Anna jested and the two sisters beamed and held each other for a little longer, never getting enough of each other's company.

"So, when is it?" Elsa asked when she remember that she couldn't actually make out anything on the page as she eyed it from beyond Anna's shoulder.

"In two weeks!"

"Did she really ask for the both of us?" Elsa asked, a little worried, and Anna pulled away to look at her.

"Yeah, why wouldn't she?"

Elsa quickly masked the worry from her face so Anna couldn't detect it and put on a delightful smile to make herself belief her lie. "No reason. I was only wondering."

Anna tried to see past Elsa's facade but alas couldn't, and so she looked over to the letter and slumped further down into Elsa's lap with guilt.

"Yeah, I guess it is hard to read. I was just so excited, I didn't want to lose it on the way here."
