This makes no coherent sense.

I don't know why things happen, I don't know how. I just know that things happen. I also know that 2000+ years ago, Orpheus and Eurydice tried to do what everybody wants to do, and failed. Arguably we make our own destinies though decision and action, arguably they are created for us when we are born and the human contact moulds our not-yet-fully-formed brains. Arguably they are predetermined by God. Logically, therefore, no matter what you believe, you must believe you cannot change what you yourself have created. Logically, if every decision (supra-natural or not) impacts on your future, everything you do is altering what will happen. And nobody can go back and change a decision they have made. Logically, I know I cannot go back. Logically, I know you don't get second chances to change what has already occurred. Nobody is perfect. Therefore everyone will make bad decisions. Every decision, every action, results in another decision and another action. Logically, our bad decisions will impact somebody else in some way at some time. In equal logic, that's not just bad decisions. That's every decision. Cheating on someone is a bad decision. Getting in a car drunk is a bad decision. Skipping an exam is a bad decision. Most decisions we make, we will not know if they are bad or good until long after we made them, if at all. Choosing a college, telling somebody something, applying for a job, going to the doctor, making a phone call, not making a phone call, saying yes, saying no. We do not to get to do it all again if turning left was the wrong decision. By the same logic, we do not get to go back and stop someone else turning left. Saying yes. Saying no. I know this. Technically, logically, actually. Technically, it's happened. Logically, I know I cannot change it, will never be able to change it, so should stop thinking about it. Actually, that's not how it is. What's scarier, is not knowing whether, if all were said and done, I would change your decision. Because things couldn't be worse if you'd said yes. Could they?
