I was bored soo...
"Aniki?" Young Sasuke asked hopefully by the door to Itachi's room. He knocked on the door three times and sang
"Do you want to go throw kunai? Come on lets go and train! I never see you anymore, come out the door. It's like you've gone awaaay~ We used to be best buddies, and now we're not. I wish you would tell me why~ Do you want to go throw kunai? We don't have to throw kunai!" Itachi who was sitting on the other side of the room said "Maybe next time, Sasuke." Sasuke sighed. "Okay, bye."
An older Sasuke laughed as he ran to Itachi's room. He knocked on the door and sang
"Do you want to go throw kunai? Or throw shuriken at the walls? I think some training is overdue, I've started talking to some of my fangiiirls! It gets a little lonely, all these fa-ake friends, just watching the days go by~" Sasuke made his cheeks sound like a ticking clock. A few days later, Itachi was talking to my parents. Mikoto looked at Itachi worriedly "Itachi-kun, please tell us what's wrong. Me and your father are worried." Itachi sighed "Okaa-san, its nothing. I am perfectly fine." Fugaku looked at Itachi sternly, glaring. "I am certain you are a mole for those Konoha fools." They both walked out.
The next scene showed a thirteen year old Sasuke sliding past Itachi's room. He stopped and looked at it, and walked away. He ran to his mother and father and said "See you in two weeks, Okaa-san, Otou-sama." Mikoto smiled and Fugaku nodded.
Fugaku and Mikoto left. They died. Attacked by unknown shinobi. Only Itachi knew they were Konoha ANBU. At their funeral, Sasuke was shedding tears. Itachi stood solemnly in the back. Itachi was now heir to the Uchiha Clan.
The next scene showed a teenage Sasuke walking by Itachi's room, where he was working on paperwork. He knocked on the door and said "Itachi?" "Please I know you're in there, people have been asking where you've been. They say have courage, and I'm trying to, I'm right out here for you. Just let me iinnn~ We only have each other, it's just you and me.. What are we gonna doooo?~ Do you want to go throw kunai?" Sasuke trailed off. Itachi on the other side of the room had a sad look on his face, mirroring Sasuke on the other side. Itachi put his hands in his face, feeling all the emotions he kept inside.
Meh. I think this one shot sucked but I like I said, was bored.
