The post above your soon-to-be post has a wish.
Let's say it's "I wish for cake."
It's your job to grant it, but with a downside to it:
"Granted, but it's the smallest and last piece of cake you'll ever eat."
On the second part of your post, it's your turn to make a wish. But be careful, it WILL be corrupted!
I'll start.
I wish that I had the power to fly!
