When someone make a "mistake" in the past and realize it, they have two choices. Whether they trying not to make the same mistakes in the future OR they to go back to the past and preventing that "mistake" to be done. And when they choose the second which is logically impossible, they find something that makes it possible. And then again even after they found "something" that makes it possible to "fix the past", they still ask to reconsider about their choices. DO YOU REALLY WANT TO PICK THE SECOND ONE? TO FIX YOUR PAST? OR THE FIRST ONE? TO LEARN FROM YOUR MISTAKES AND NOT LET IT HAPPEN AGAIN IN THE FUTURE? So, which one do you want to "Fix"? PAST or FUTURE?
