snape killed dumbledore, bellatrix killed sisrius. their both dead. they aint coming back. get over it. and you know what? jk said she was killing someone in the 5th book and she cried while writing it. who was killed? SIRIUS. so he aint coming back. jk is killing off EVERYONE harry feels can protect him, so he can learn to protect himself. right? Dumbeldore. remember when he said he saw himself with a pair of wollen socks in the first movie? and harry thought he was lying. well maybe dumbledore is in fact the happiest man on earth. and it is sort of said that the happiest person sees only himself. and they dont come back as ghosts. well dumbeldores not a ghost and he's happy. which is why he died. happy. period. theyre both dead.
