I would try to change the world, however... that's not how it would end up.
If so then I would rob a bank during business hours and take high denominations bills from the vault. Hopefully - this would be during the summer so I don't freeze to death walking around naked-invisible.
I would tell you but it would bring to the surface a deep seated perversion of mine that I prefer to keep dormant until I have ceased to exist. I think that would be best for all humanity concerned.
I would beat the crap out of everybody that has lied, used, and got over on me. And I would be talking to them invisible while I was whipping their donkey telling them why. And since I would be invisble they would be too afraid to tell somebody an invisible person beat them up because the person they are telling would really think they were crazy.
If I were invisible for a day, I would prank everyone I know. I would make them think that there was a ghost in the house, and freak them out, until I called them on my cell phone once I got back home to tell them that it was me pulling a prank on them. Sure, they'd be mad at me for a while, but they'd eventually forgive me (I hope!).
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
