What have I done?

Dashie's POV

I kneaded the black Icing bag, and then squeezed it out onto the purple cake, completing the words:

"Happy Birthday Brett"

Suddenly, just as I was moving the cake onto a silver platter, I heard the front door of my apartment slam open. I quickly hid the platter behind my back as my brother walked in.

"Dashie! I have a great surprise!"

"Really? What a coincidence! I do to!"

"Really? You go first!" Brett told me. I pulled out the cake from behind my back, and placed it in front of him. "For me?" He gasped.

"Happy birthday little bro." I ruffled his hair.

Several came slices later, I remembered something.

"Oh! What was your surprise?" I asked Brett as he desperately tried to get his pocket watch onto the new gold chain I had gotten him.

"What? Oh yeah! Dashie, I GOT INTO THE STUDY PROGRAM!" Brett was practically exploding with excitement.

"The one in Phoenix Drop? Really? Brett that's great!" I gave him a huge hug.

"There's just one catch. They only have space next semester. Which means I have to miss your exam. I'm so sorry." I smiled at him

"That's ok- wait. THAT exam? The final exam that I need to pass in order to get my exploration license? The fighting monsters until you pass out exam?" The realization sunk in.

"Yeah, that on." Brett's face was a mask of calm.

"BRETT! YOU PROMISED YOU'D BE THERE!" As I processed the information, my rage grew.

"I'm sorry...." Brett was clearly panicked.

"FINE! GO! IT WASN'T LIKE I PLANNED ON DEDICATING IT TO YOU OR ANYTHING!!!"

"Sis. Calm down."

"DO BRETT! JUST LEAVE. GO. I DON'T WANT TO ASSOCIATE WITH PEOPLE WHO BREAK THEIR MOST IMPORTANT PROMISES."

"You don't mean that Dash." BRETT's voice was barely a whisper. Tears were streaming down my face.

"AFTER MOM SAID SHE HAD BETTER THINGS TO DO THAN SEE ME GRADUATE, YOU PROMISED ME THAT YOU AND I WOULD STICK TOGETHER! BUT I GUESS THAT'S NOT IMPORTANT ANYMORE!" I stormed out of the dinning room, my cake half  finished. I slammed the door behind me, then sunk to my knees.
