Why...sister?

Tia walked in to an astonishing sight. The walls cover in a new paint, the color of Luna's royal blue coat. Band posters graced their walls some being not to pleasant. Loud music busted her eardrums. She opened her eyes and stomped her hoof down, demanding why this was happening. Luna turned around, looking at her sister, scolding her almost. She was about to be 13, and she was acting like a complete idiot. Tia noticed something different about her sister. It wasn't her dark mane with light blue and hot pink streaks, nor was it the makeup she was wearing, which wasn't to hard not to see, but it was her face, something wasn't right. She couldn't pin point it, Luna had always had such a beautiful face, but something was throwing her eyes into a frenzy. Then she finally noticed, her mouth had a-a-a piercing! And so did her ear! Tia froze,  gazing at the piercing, which stuck out like an watermelon on a apple. She spoke up, still with a small, rationed panic in her voice.

"Luna, what is the meaning of this?" She asked in a worried tone.

"What is the meaning of what?" She growled back.

"Th-th-the piercing. Why do you have a piercing?"

"Cause I wanted one. Got a problem with it?"

"Well..."

"Listen, just shut up. Stop interfering with my personal biz, and everything will be 'Howdy Poody'."

"Lulu! How dare you talk to me like that!"

"Its Luna, not 'Lulu' you idiot, now back up I'm going to a 'Master of Puke' concert."

"Oh' Luna, those guys are meant to be heard by fillies your age." Tia put her hoof onto Luna's shoulder.

She immediately smacked it off, " I can go do whatever I want. And get your gross hooves off of me. Why the hell to do you even care. I'm practically a teenager, and your practically always annoying. Mind your own damn business, and get out of my way!" She stormed past Tia, quickly exiting the room. She hung her head down.

Tia was up late waiting for Luna. She was writing in her journal. "Ugh. Luna has been acting out lately. She is breaking rules, breaking curfew a and breaking hearts, mine especially." Her eyes began to fill in tears. "Our conversation has gotten me thinking, what if Luna will stay this way, hopefully not. I want her the way she was, a sweet little filly, without her goth or emo look she is trying. She is turning into a punk I feel like. I wouldn't be surprised if she came home with a police escort." She tingled with that thought. "Luna, come home, be the way you used to be. I miss my little sister, I miss her a lot." She started to tear up more and more, the previous tears flowing freely, she managed to sign her insignia to the page, put the quill down, and went to sleep, her eyes still tearing as she fell asleep with a quiet sob.

Tia woke up in the middle of the night. Red and blue lights flashing. Luna was home, most definitely. She walked into the room where mom, dad, and Luna along with the police were standing. They explained to her parents about why Luna got arrested. It was for breaking curfew, vandalism, robbery, and destroying property. They explained she would need to go to court, and have this talked out with the judge. Tia could only silently watch in the background, her eyes welling up.
