Is it wrong to compare going back in life to going back in a book? Flipping the pages back and thinking the words may have changed, or watching a movie over and over expecting a different ending? I used to go back - stop the DVD at a certain part and replay it, but of course, the ending was always the same. Sure, there are certain films that contain alternate endings, but those are few and far in between and most people hate the alternate endings, anyway.
I've decided I'm not going back. The endings are the way they are for a reason. The past isn't the present for a reason. "What if's" are called just that for a reason. They're fun to think about, but that's where it should be left. I'm comfortable with that idea for the first time in a long time.
