When I saw this thread title and the opening post, I knew exactly which hour from my life I would love to re-live. I have few regrets in my life, and it is very much out of character for me to wish I had made a different choice ... but if I could undo the heartbreak I caused my wife some years ago, I would do it in a heartbeat. I can't change the past. I can change the future. So that is my new focus.
