Honestly I wouldn't want to do any of them. I have no romantic interests whatsoever. I don't believe in bringing back the dead. And I don't want to mess with something as complex and intricate as time.

^ Agreed.

The Laws are there for a reason.

I'd use it to stop my brother from ever becoming a drug addict, ruining his life, and ultimately dying five months ago thanks to his problem. Plus, I'd like to be able to have us actually be close when I was growing up, since he spent most of his time with his brother and sister from his mom's side. As Regina would say, if it means messing the delicate balance, "than so be it."

I'd love to bring back the dead...there are so many people who die too soon (in my life anyway).

Or change the past.

Definitely this one.

Probably "Change the Past" as well, because there are so many things I wish I had done.
But this would be my first choice because then I could revive a friend of mine who died of cancer.

I think everyone would want this, even for "just in case" purposes if they hadn't lost someone.
