Born To Be Mild.

"Ma'am were you aware that your suitcase is full of rocks?" A young stallion with a sandy blonde mane, dressed in a train station uniform asked as the last case he put away didn't only weigh a ton but popped open to reveal nothing but stones.

"Yes I was aware. Please do be careful I can be a little 'Sedimental' about them." Maud replied never batting a lash, the stallion merely gazing back a bit confused before getting back to work.

"Leave it to the Rock Queen to bring the rock farm with us." Limestone smirked as she nudged her baby sister on the side softly.

"Mmhmm." Marble giggled as her older sister gazed out the window for a second. Her pale green eyes watched the many ponies walking by with their daily lives, each free to explore and discover.

Limestone bit her lower lip slightly, with such a large open world around them filled with countless ponies and stories. Did she feel her world was just a bit small, she loved the farm with all her heart.

But was there more?

Limestone found herself looking at a small filly with her parents near the exit of the train station. Her red mane was frazzled but she looked absolutely joyous, her father went as far to stop the child from picking up their last bag, happily carrying it himself.

The child's hooves were so clean, never knowing a day of hard work.

The grayish blue mare gazed down to her own in silence, so rough with calluses and hardened by stone. Her symbol of the rock farm.

"Mmmmmhm?" Marble gently nudged her sister back, the sudden silence from her out-spoken sister worried her just a bit.

"Hehe. I'm ok little sis...just drifted off for a second." Limestone smirked as she relaxed within her seat, the train echoing with a loud whistle into the bright blue sky.

Soon the train began to move and they were on their way. The engine pushing against the tracks as the world around those within the carts became a blur of landscapes. Limestone let her eyes fall to her little sister again, she could tell by just a glance she was worried about something.

"Maud told me Pink hired you on for a job."

"Ummm..." Marble simply whimpered out not sure what to say.

"Hey! it's ok by me, Pink wanted the sister with the light touch for this one." Limestone smirked as she gently brushed the bangs away from her little sister's eyes.

"You need to open up some more anyway. Sometimes I feel like I'm talking to a stonewall." The older sister giggled as Marble huffed aloud.

"I can't help it! I'm just not the talkative type...what if I say something dumb or if ponies laugh at the way I talk?" Marble groaned her mind racing with inner thoughts.

"Sorry kid if I come off a little harsh. I just know you have a fiery spirit hidden within you." Limestone spoke as she slid lower into her seat slightly.

Marble scrunched up her muzzle cutely, pointing to herself as her sister just burst into giggles.

"Yes you!- you might not see it but I do! You have the fire inside to light up the world!"

"Ummm."

"It's a rare thing to have. You just need to learn to take a chance and jump into the world!" Limestone smiled her voice rising a bit as ponies quickly glanced towards them out of curiosity.

"Because before you know it...the world has passed you by." She trailed off almost into a hushed tone gazing back out her window.

"Do you want to talk about it? I know you try and act all scary but I want to be there for you." Marble felt her mind echo with those words.

Gently she lifted her own hoof to place atop her sister's. Maud's voice suddenly calling to her from across the aisle, the seat next to her open and for the taking.

Marble decided maybe Limestone just needed a bit of space. Softly sliding off her seat she walked over to Maud taking the spot at her side and smiling brightly much like the sun outside.

"Is everything alright? I noticed Limestone had the same look as Boulder when he thinks about his old quarry." Maud spoke with a soft pitch, reaching into her pocket taking out her polished and loved pet rock.

"Umm." Marble tried to find the words to best describe the feeling she was having at the moment.

"You're worried about her that much huh?" Maud shrugged as she gently stroked her rock in her hoof.

The young mare let her eyes widen in shock at how her sister was able to read her so easily.

"I know you're thinking how I did that. Simple your eyes, they show more than words could say." Maud gave her sister a blank stare as Marble just returned a look of awe.

"Did you know Marble is a strong and durable stone? It can be placed almost anywhere and bring a air of beauty and grace with it." Maud slowly let her hoof come to a stop, pale hues gazing over to her baby sister.

"But being as strong of a stone as it is. Marble can easily be scratched or stained by the weight of the world around it." Maud swiftly slid the rock back into her outfit, placing her hoof onto Marble's afterwards.

"If at anytime you feel like the weight of the world is getting you down. Let me know ok? " Maud slowly flashed a small smile from her usual indifferent gaze.

Marble sat there in silence as she simply nodded. Her mind was racing with many thoughts, she wanted to share with her sister but at a time like this? It was supposed to be a vacation, a time to have fun and enjoy.

She would soon discuss a few things with Maud, but perhaps near the end of the week. For now she just wanted to have a good time, forget about all the un-ease she felt within and think about happy things.

She wondered what Pinkie had in store for them once they arrived. Maud had spoke of her first visit to Ponyville and how Pinkie nearly got crushed by a large boulder. Though Marble didn't want that to happen, a part of her wished Pinkie would do something crazy again.

So just maybe she'd be there to catch all the laughter her sister was able to bring to the ponies around her.A gift she more than once dreamed of having, to be able to speak your mind and not fear what others might think.

As the train sped ahead towards its destination, her mind began to wander.

Would she be able to be graceful and strong to make Pinkie proud this week?

Or would she just end up being stained by the weight of the world?
