> Hmmm...I'm thinking there has to be more to it than that. The 
reason I'm thinking this, and I'm kinda suprised no one has brought 
it up is remember in POA when Hermione forgot to go to her Charms 
class. When Harry and Ron remind her of this she's very upset about 
having missed it. She doesn't simply turn the time turner back a few 
extra hours and attend charms. Why?

 The whole idea of time-travel is simple, yet the idea of changing 
history is impossible because in your past history, the present(or 
future) you would have gone back just as u were then to change is 
and ur life would be the same. nothing is changed that hasnt been 
changed before. its so complicated that in my head i undertsand yet 
when i try to explain it to people i feel so lost of words. Its as 
if fate knew u were coming back because u always do in every life, 
and you cant change that because fate brings you to the point where 
you travel to the past and change(or not) something(or nothing) 
complicated when in words. fawkes(pat)
