I wish for a dinosaur pet.
Granted, you'll receive a Tamagotchi in your birthday.
I wish to read people's mind without my head exploding or other painful things.
Granted - nothing painful will happens. Still every single time you read someone mind some of his personality overwrite yours. In time there is no more you - just a thing that reads minds.
I wish for us to stop wishing before some of those things will start happening
I hope participants know I am waiting very eager for that "corrupt a wish" version ;)
