"so if something happened, it's not ment to be changed"
Strange rationale.
So if something happens and there's an opportunity to change it, what then?
Cause and effect and coincidence are all there is. If you do something, there will be results. When you think of every single intricate development in every single human beings life that somehow effects someone else, coincidence is impossible to avoid. I was walking across the road once and my friend called me, I stopped, A truck crashed right where I was standing. Everyone went "oh that's fate, that happened for a reason." My friend said "No, I was on the phone, saw him walk past the window, Chris had to hang up coz his mum was bitching at him and as a result I walked out to call him."
Nothing more, nothing less.
