I found a bag of wishes once. They were ok, they weren't my own; but many were bright and beautiful. Others dark, unpleasant and cold to the touch. I laid them out on my table and watched them squirm and try to be born. Many died as I looked at my watch. Others burst to fruition and vanished to destinations unknown.
Unfortunately they were mostly the dark ones.
I swept up the remains once they had all fought out their lifecycles. It was sad to see them in the trash next to the pizza box.
I kept the bag, I might put something of my own in there some day.
