Maybe Tobi was trying to say that his one important wish was to stay and lived with Rin and the second was to become a hokage, but since Rin died, all of his wishes become crushed even the hokage part. Because he loved her so much and want her to see he's become a hokage like he promised

true so true

well the part of happiness Earth has is when the one person that is a person actually does all he does for kindest towards but is still a badass

Not all but some wishes get granted.

But ... But ... I once wished for a Cola and I got it D:

'Everyone wants some magical solution for their problem and everyone refuses to believe in magic."
