Nothing so grand, for me. I think I'd go back to when I was a teenager to see my sister for a bit. She died in a car accident at age 18. I am not sure how my life would have turned out if she'd never got into that car, or if it would affect having my kids. Because of that, I would be torn between saving her and risking that they would never come into existence (the first was conceived in grief - and love of course). If I could keep my kids, wouldn't it have been wonderful to have her with me while we grew up and raised families? I still miss her, everyday. I'd settle for just a few moments to hug her, tell her I love her and say my goodbyes (without letting her know it was goodbye, of course).

Actually, we'd probably end up getting into a sister spat over who used up all the hot water.
