At some point you made a wish, you said "I know to know it all" all-of-a-sudden your head explodes b/c God granted that as your only wish! Then you then go to heaven and try to contest your death saying you never said "i wish". God thinks about it then agrees and sends you back to earth but a few moments earlier so now there you are. Not really your fault but you have no more wishes, not even wiser for the wear!
Hey, I don't make the rules, I'm just trying to help you guys understand why wishes don't always come true. Sorry about that (for you poor suckers who had something like this happen to you with out you knowing).
