Time

"There's the funny thing about time... The problem is it's just too chronological."

Back when I went to church, one of the pastors said that. He looked exactly like Chandler from Friends. He was the only one I ever respected there. If time travel were possible, but you could only go back and fix one thing one time, and you had to live with the result no matter what, would you? And what would you change? It might suprise you if you think long enough. You might not want to risk a bad outcome, so you avoid ever entering the situation in the first place. Think about that. Rather than fix or fuck up one thing, you'd rather have never known a whole person. I probably would, wouldn't you? You'd throw away all the good things to live without the mistakes. Now what if I said you'd lose your memory during the time travel? What if I said that you wouldn't recognize anything that you'd already done before? I'd bet a billion dollars you'd repeat the exact same mistakes again. Maybe we have time traveled, but we'd never know it. Makes me question, do you believe in fate?
