Hey, everypony! :D This is my first fanfic based on prompt words, so I'm not too sure about this...still, I'll give it my best shot. :3 Enjoy! :D
Rainbow Dash awoke from her regular nap slowly, yawning loudly. It was a Tuesday afternoon, and all the other ponies were probably busy. But not Rainbow Dash. She'd finished all her weather-related tasks for the day, and now she could do whatever she wanted for the rest of the day and, for the most part, she spent that extra time practicing for her moves and technique, if the Wonderbolts were to ever show up and see her. But, after a lot of hard work, she would usually take a nap afterwards. She didn't want to overwork herself. After all, the Wonderbolts wouldn't be impressed with a tired pegasus. She had to think about her performance. She was about to fall back into the gentle arms of sleep, when she was taken away from her dreamy thoughts by a familiar voice.
She groaned, then started falling back to sleep again, ignoring the shout.
"Come on, you sleepyhead! Wake up!"
The voice was louder now, and more concentrated. She stretched properly, making sure all the muscles in her wings were carefully adjusted. After that, she stood on the cloud and looked over the fluffy whiteness, the very image of grumpiness. However, the pony who had called Rainbow Dash seemed unaffected by the athletes reaction, and only smiled up at her, bouncing on the spot happily, her bright pink mess of hair bouncing with her, as if it lived independently, and her pet alligator Gummy poking it's head out of the pink bag she carried with her, as neutral as usual to all that was happening around him.
"Pinkie Pie, what is it? I'm trying to sleep!"
"Rainbow Dash! You're awake! At first, you weren't waking up, so I just kept calling you, and then I thought about taking my air balloon up there, and then I realised I'd left Gummy back home, and I was so worried that I ran all the way back home, and when I'd come back here, you were just waking up, so I started calling you again, a-"
At this point, Rainbow Dash had slowly flown down and put a hoof over Pinkie's mouth, who continued to smile, either oblivious or uncaring of the pegasus's attitude.
"Pinkie Pie. What did you want?"
"Mm mm mm mm!"
It was at that point that Rainbow Dash remembered that her hoof was still on Pinkie Pie's mouth. She sighed and moved it away, mentally preparing herself for the surge of randomness that would proceed to spurt from her friend.
"Oh, yeah! I was just walking around when I saw this poster for an art class, and I was hoping you'd come with me!"
Pinkie Pie finished with a grin, looking up at Rainbow Dash was a delighted face. Rainbow Dash sighed in response.
"Pinkie Pie, you know I wouldn't be interested in that kind of stuff. Why did you ask me? Can't you take some other pony?"
Though she was rejected, the grin didn't appear from Pinkie Pie's face as she tried again.
"Come on, Dashie! You never know, you might end up liking it!"
"Pinkie Pie, I can barely handle writing simple words with my mouth, let alone sticking a paintbrush in there! I'm the greatest flyer in Equestria, not the greatest painter!"
Pinkie's hair started to deflate and she looked to the floor.
"So does that mean you won't go?"
Rainbow Dash was about to reject her offer completely when she remembered how Pinkie Pie would go to every one of her flying events. She felt a stab of guilt, and sighed. Stupid Pinkie Pie, she thought. She'll get in the way of my dream one of these days. She sighed and grumbled her response.
"Fine, I'll go."
Pinkie Pie, in her usual unpredictability, pounced on her, hugging her so tightly she could barely breathe.
"Yay! Thanks, Dashie! Don't worry, you're gonna have the best time ever!"
Pinkie Pie suddenly let go, allowing Rainbow Dash to gasp in some air.
As Rainbow Dash started to recover, Pinkie Pie grabbed her and began to drag her off.
"Come on, slowpoke! To the art class!"
"Who you calling slowpoke? And I can get there myself."
Rainbow Dash stayed low on the ground near Pinkie Pie, flying slowly as Pinkie Pie jumped up and down and continued to ramble.
