(Ninjoc, I can assure you I will never take a story from a fellow author, and I can also assure you that the plot is much different then yours, so feel safe! I'm gonna read your story too, at first glance it looked good)

The next day:

"Get up!" A voice woke up Koskate. Koskate tried to remember what happened last night. All he did remember was a big room and-
His thoughts were ended by something hitting his back, and shocking him. "I said get up trainee!" there's that voice again, so Koskate thought it best to get up. "Better trainee, now move! Double time!" Koskate ran outside and saw his name, CPO Herandez. "Good you're the first one out." He said looking at the building. Soon other children came out at the double time march.

"OK! Get into lines of 15!" CPO Herandez ordered. The children moved into place. "Let's work on some exercises," he said looking at all the children's faces. After two hours of non-stop work the children got a break, with water. "Now time for school," he pointed to a building, some two kilcks distant, "Double time!"

The children reached school, out of breath.
"Welcome Children, I'm Deja, your teacher" said the A.I. "Please come in..."
Most of the children made a move to the door.
"Those who don't want schooling may exercise with the CPO. "Deja said. This got the rest of the children moving. When the children entered the building, they were amazed. The classroom looked just like a meadow.

Soon the environment changed. There was an army of people advancing on a much smaller group of people.
"This is a battle from history. The smaller group of people were known as the Spartans. They were trained from childhood to fight in battle." said Deja as the Spartains slaughtered the army. "Now that's it children, The C.P.O. will take you to the playground" she said as the doors opened. Some of the children got excited. Deja then herded the children outside.
"Ok it's just a short walk to the playground. Now let's move, double time!" he ordered. The "short walk" turned out to be 3 klicks long. The "playground" also included about 100 wooden poles, each of different height. "The game to day is to reach the top" he said pointing to a pole some ten feet higher than the rest. "Now, get into three lines" he commanded, the children obeyed. "Now look to your sides, these are your teammates, you have to you them in order to get to the top, the first ones up get extra dinner later" he said," but the last ones...they get no dinner"
Koskate looked at his 2 teammates
"Hi, I'm Ayami" said the girl
"I'm Hichro" said the boy
"I'm Koskate" he said, "And...there appears multiple ways to get up there"
"Well, chose the fastest way" said Ayami
"I got it, first we..."he laid out the plan. Right as he finished the C.P.O. yelled "Go!" all the children shot off. The group of three was in the lead, but was the third group to get the bell, when they hit the ground; they ran to the start line. When they crossed it, they looked around and noticed that they were first. They waited for the rest of the teams, then went to have dinner, roast beef, green beans, and just about everything else you'd find at a thanksgiving feast. Koskate ate very quickly. Ayami didn't eat much. Hichro managed to control his speed.

And that was five years ago...
