It is the Chinese belief that, if you burn something, it will reach the departed person you intended it for.

Obito,

My father raised me to be one thing: shinobi. I thought everything would be fine, because we could handle it.

Then my father was pushed to suicide because he saved his own comrades.

Then you two joined our team; Rin and you. I know I was hard on you, and especially you, Obito. You went against everything I had been taught to be, and I believed that spelled disaster. That you would be the death of us all, or yourself, and I couldn't accept losing a comrade. Even one like you. Yet I now see that I cherished our time together, even though I never admitted it to myself. You three meant everything to me then, and that might have made me even harsher on you, especially once the war started.

Then you died.

The war seemed to just drag on, no matter what we did. With Minato-sensei, we started winning again, but it didn't seem to make much difference. Iizuka, Konegi, Matsura; we kept losing people we knew, and it felt as if there would be no end.

Then Rin died.

I can't tell you much about the war effort after that. Gai tried to keep me sane. I remember Minato-sensei trying to talk to me, but he had quite a lot to deal with, too. And it dragged on and on. And then... it ended. I remember blinking at the Sandaime as he announced the ceasefire and that peace negotiations were being put forward. Gai hugged me and roared something about the power of youth, while Minato-sensei just stood there, smiling quietly.

I didn't take part in the celebrations, but it still felt nice. I was starting to think that the world might finally calm down.

Then the Kyuubi attacked, and Minato-sensei died.

I've seen a rebuilt Konoha lain to ashes thrice now. I've seen young children slaughtered, murdered, burned and trampled. I've seen older people aplenty dying in the same fashion. And, just when it seems as if things are finally starting to heal, just when everything seems as if it's going to be okay, something else happens.

You gave me your eye so we could see the future together, Obito, but, sometimes, I wonder if the future is worth seeing at all.
