[ Kakashi shrugs a little. ]

I guess I thought being a soldier would be fun. I mean, I was just a stupid kid, anyway.

[ Actually, that's not true at all. Kakashi enlisted because he couldn't bear the thought of being without his brother. He was afraid that Minato would enlist in the military and never come home. And even if Kakashi was only fifteen years old, he wanted to protect him. ]

Besides, my older brother enlisted at the same time, so I though it'd be a good idea to stick with him.
