I have such overwhelming longing for a chance to go back and things to go differently to get a different outcome - but even if time travel was possible, I couldn't change things anyway because the stuff that impacted my life was significant bereavement and my own serious health issues. So going back in time wouldn't fix anything, and I'd just be waiting for the deaths to happen etc with a sense of dread
So it doesn't really make sense at all!
Meeting DP was the best thing to happen to me later on, so I'd ensure that meeting still happened 
If you could rewind and do anything differently, would you? Or like me, would there not really be anything much you could do to end up in a different place?
