Kakashi always late! >_<"?
Haha, I think I realized why Kakashi late.Or always I have a theory anyway. Do you remember what it was Obito later than we have seen in the manga? And Kakashi is always late now, and it was before I got Obito's eye. So did some Kakashi Obito sliding? XD I do not know, I just think about it. I know you visit the stone monument much, just came to my mind.
Remember that episode. . . I think it was after the Hokage died, we saw Kakashi standing in front of a tomb? I thought it was too late because we will always Obito's grave.
