Think about this -

What would happen if you could think bad thoughts about someone who has done something evil to you? What if you had the power to just think of something awful happening to them, and BANG! It does! If the whole world had this power, than I am sure the evil nature in us all would lead to the extinction of mankind. But what if just one person had this power, or curse? That is going to be the subject of my next story I write. I got the idea from one night about a month ago, when some genius decided to key my truck for no good reason. I wished I could get even with that person, even if I could never know who actually did it. Then I thought of this idea for the story; only in the story, the main character who ends up with this power, discovers that the power is more of a curse than anything else, because people he cares about begin suffering.
