I don't even own this laptop-

The kids chorused in laughter and cheer as the final bell of the school year rang. The bright blue sky was practically on it's hands and knees, begging everyone to throw themselves out the classroom window and roll in the grass. Or...maybe that was just Mabel.

Mabel bounced in her seat with excitement. Today, her face was going a million smiles per hour. In three days, it was goodbye California and hello second summer spent at Gravity Falls! But this time, with no Bill to bother them. Dipper and herself had been going on and on about everything they were going to do.

Dipper wanted to do boring poop-head things like discover more mysteries, but Mabel wanted to roll in some more grass and let Gompers reunite with Waddles.

"Have a nice summer!" Ms. Harrison, a small chubby middle aged woman, saluted the students a fair well.

The girl hopped off her seat, pouring her glittery pens into her backpack for the last time.

Mabel pulled a rubber band off her wrist and wrapped her hair in a bun, tying it up to withstand the California heat. Dipper was in a different homeroom, but she just knew he was waiting for him by the water fountain.

"Miss Pines?"

Mabel perked up at the sound of her teacher's voice. "What's up, Shelby?"

"Don't call me Shelby." Ms. Harrison sighed, "It's about your thesis on Darwin's Theory on Evolution."

Mabel scrunched her eyebrows up, "Dar...huh?"

"You didn't do it, did you?" Ms. Harrison said in a monotone, obviously not surprised by Mabel's lack of effort.

Mabel shrugged, "Oh well."

Ms. Harrison sighed again, a sound continuously used when talking to her, "Mabel, that assignment was worth thirty points on your average."

What's an average? Mabel wanted to ask, but she'd hate to come off as unintelligent.

"That means, you have summer school."

Mabel's face turned cold at those words. Summer school. No, no, no, this summer she was supposed to be going to Gravity Falls.

"C-Can't we, reschedule summer school?" Mabel asked nervously, "I'm going on a very important trip."

"You should've thought of that before you decided that you were too important for my class." Ms. Harrison retorted, handing her an envelope to give to her parents with the news. The teacher hobbled away, leaving Mabel in the deserted classroom.

Mabel couldn't move. The trip she was waiting for all summer was ruined. And it was all her fault.

The classroom lights dimmed, as did her spirits. The lonely child titled her neck up to prevent any tears do glide down her face.

"What am I going to tell Dipper?" She asked aloud.

Dipper and Mabel walked home together, as they always did. Dipper talked the entire time, chirping and fantasizing over their second magical summer in their favorite place town.

"I was thinking Soos and I could make sling-shots with your training bra, and we can have a tournament with Stan and Ford. That sounds fun right?" Dipper nudged her.

"Yeah..." Mabel mumbled. It sounded amazing. The real Mabel would've jumped ten feet in the air at the idea, she enjoyed using her under garments as weapons. If only she could...

Dipper practically shot through the door once they arrived, "I'm going to start packing!" He said with a smile, running up the stairs. Mabel leaned against the door frame and groaned.

"Hey, Mabel!" Her father greeted her with open arms. Mabel didn't budge. The girl frowned and pulled an envelope out of her sweater.

"I have summer school." She admitted. Mr. Pines scanned her teacher's announcement, his eyes narrowed as his pupils moved left to right.

"Hmmmm...mmm...mhmmm..." He muttered, "Uh, why don't we meet at the living room with your mother?"

Hand in hand, Mabel and Mr. Pines walked into the living room, finding Ms. Pines knitting a blanket. Mabel liked to think she inherited her love of arts 'n crafts from her mother, as they were both very talented at it.

The baby-blue blanket was almost complete, it draped over her lap. "Hey sweet-hearts" she said, not looking up from her knitting, "Excited for your trip?"

Mabel winced at her poor choice of words. "Actually..."

Mr. Pines handed his wife the letter, allowing her to skim over it.

"Oh my..." was all she could say. Mabel pulled away from her father, belly flopping on the nearest bean bag next to the couch. "Can I please go to Gravity Falls instead?"

"I'm sorry, pumpkin. Your education is more important, you can't go to Gravity Falls this year." Mr. and Ms. Pines sat together on the couch, rereading the letter a few more times.

"But school in the summer? Why would you do that do me?" She cried, tears sliding down her red nose.

"You did this to yourself" Her father snapped, "Why couldn't you do your assignment?"

Mabel flushed, twirling a loose piece of hair around her fingers. She never forgot about the assignment. She tried her hardest, but she simply wasn't smart enough. It was a terrible thing to think about herself, but she couldn't help was repeat the phrase over and over. She got summer school for Pete's sake.

Mabel settled with a shrug, mortified by how her biggest insecurity was going to cost her the entire summer.

"I guess that means Dipper can't go either." Her mother said.

Mabel's eyes shot open, "Woah woah, what? Why is Dipper getting punished?"

"He's not getting punished!" Mr. Pines held his arms up, trying to calm her down. "We can't just let him go alone, it wouldn't be right. Dipper would get lonely."

"That's stupid!" Mabel shouted, "Dipper has plenty of friends in Gravity Falls, why do you have to bring him down because of me?"

"Do not talk back to your father!" Her mother's expression turned cold as she snapped. Mabel huffed and crossed her arms, fluttering her damp eyelashes.

Sniffling, Mabel tried her hardest to explain herself but was cut off when both her parents called her brother's name.

Mabel gasped, "Mom, you really don't have to-"

"What's up?" Dipper hopped down the stairs, a temporary smile painted on his face. His eyes were shining, like he just heard a funny joke. "I was just packing for the trip, Grunkle Ford is going to freak when he sees my new project."

The edges of Dipper's mouth turned downwards as he scanned his kin. His sister was pale, her usually rosy cheeks now chalk white at the sight of his optimistic face.

"What's wrong?"

Mabel's stomach tightened. Lowering her gaze toward her shoes, she grabbed the ends of her hair and intertwined them in her fingers.

Mr. Pines released a long sigh, "We...well we're going to have to, I think it's best if we-" their father faltered, never being comfortable with being the giver if bad news.

"You guys aren't going to Gravity Falls this summer." Ms. Pines ripped the band aid off immediately.

Dipper body tensed up at the words, his face growing pale. "Wh-what?"

Ice ran through Mabel's veins, shaking her small frame as she embraced her legs. She just had to stay quiet and look as shocked as he did. He couldn't think she had anything to do with it, it'll only make his mood worse.

"Dipper," his father said cautiously, "I'm so sorry-"

"WHY NOT?" Dipper yelled, his shaky voice startling them all. "You said...you...you promised! I can't, why would-" he paced around the room frantically, his breathing increasing alarmingly. Dipper's eyes had grown puffy, like his own eyes were absorbing the tears. His voice grew higher louder and more shrill with every word.

Mabel gripped her knees, clenching her teeth tighter to imprison her choking sobs. She messed up Dipper's entire summer, all because she was lazy.

Mrs. Pines turned her attention toward Mabel, her eyes flashing with disappointment, "Mabel, would you like to explain this to your brother?"

Mabel shrunk, grimacing as she felt the heavy silence she was trying so hard to avoid. Dipper gave her a quizzical look through his tearful mask, probably asking himself why Mabel knew about this before he did.

Wondering what she could've possibly done wrong.

"Mabel?" His small voice broke down her walls, allowing her unwanted sobs to escape.

"D-D-Dipper-" Tears puddled under her eyes as she trembled, "It's my fault..." her confession cut through her throat, rocks filling her lungs.

Dipper's posture straightened with concern, "W-What do you mean? Mom, Dad, what is she talking about?"

"Mabel..." Her mother gave her a stern look, pushing her where she didn't want to fall.

"I got summer school, Dipper." Once the wound is open, you had to let it bleed, "It's my fault."

All Dipper could do was stare at her, possibly the worst thing he could do. His expression morphed from shocked, to sad, to betrayed. Until finally, it settled onto furious.

"Are you kidding me?" He threw his hands up in the air, exasperated, "We had one more day, one more day until we finally got to see our great uncles again and you screwed it up! All because you weren't smart enough to handle a simple assignment!"

"Dipper!" His father warned, cautious of his sister's feelings.

"No! I am not going to sugar coat this, this was going to be the second best summer ever, and you ruined it! You ruin everything!"

Mabel could feel herself falling apart under every word. This couldn't be happening, he's never hated her this much before.

"Apologize right now!" Ms. Pines commanded.

"NO!" Dipper looked Mabel right in the eye, "Mabel has been ruining everything left and right, and I'm always the one that has to be the first to apologize! She is always seen as Little Miss Innocent and I have to be the shoulder she cries on, but the truth is she only cares about herself!"

Mabel took a shaky gasp and stood up. Her cheeks heated up, coated with glossy tears. Her chest heaved with every breath as she stared at her brother with disbelief. Dipper shot daggers, his fists clenched.

"The one time it actually counts, the one time it matters, you mess it up! Why do you have to be so selfish?" He spewed is last bits of venom at his twin before she ran upstairs, her sweater sleeve covering her eyes.

She couldn't see anything. Nothing but the sleeve of her sweater and outline of the stairs. Her footsteps slammed against the ground like thunder as she stormed into her room, praying the floor wouldn't fall through. She felt thick trails of warm disgusting water fly off her cheeks.

Fighting exhaustion, Mabel threw herself onto the nearest bed and let it out. Her eyes damped the thin blanket supporting her, pressing against her face as if trying to pour tears back in.

Mabel screamed, her voice muffled against the fabric. She screamed until her lungs strained in her neck, until her body shook with weakness.

Stupid

Selfish

Lazy

Everything she knew was true, spat right in her face by her own twin brother.

She was the one who failed, not him. It's not fair that he had to be left behind because she wasn't smart.

Mabel pulled her face out of the bed, her cheeks burning. Out of place hairs stuck under her eyes. She blinked them away, sniffing wetly as she looked down. Gazing away from her fingers, she noticed blue fabric underneath them. Her blankets weren't blue...

She stood up in horror, this was Dipper's bed.

Dipper.

His words echoed in her mind, each flaw of hers called out. And in front of her parents.

The stress plummeted upon her shoulders as she threw herself back onto his mattress. She sniffed his blankets. They smelt like baby wipes and sweat, but all she could do was sniff harder. She knew he'd never talk to her again, Gravity Falls meant so much to him. He was so elated to have been able to return for another summer.

To bad dreams die.

"I'm sorry..." Mabel whispered into his fabric, her face becoming blotchy and red. "I'm sorry, Dipper..."

Tears swam down her cheeks, leaving tracks of dry skin from the makeup they wiped off, "I really am a screw up, am I?" she said.

The walls closed in on her as she clutched the blanket tighter. She didn't want to be a screw-up, her stupidity was just inevitable.

It's just how it had to be...
