"I wish that I would meet a dwarf." After the stone glowed, Jon heard a voice.
"Okay, I'm here. Are you happy?" the gruff voice said.
Jon looked around.
"Down here."
Jon looked down and saw a short stout man with a long beard crawl out from underneath his bed.
"You're really a dwarf?"
"Yeah."
"What were you doing under my bed? Do you live there?" It stunned Jon to think that a creature had been living under his bed this whole time.
"No. Of course not. I just like to hang out there. I like dark places."
"Then ... where do you live?"
"Well, obviously underground. I am a dwarf, you know."
"How did you get in my house then?"
"Through the basement."
Jon suddenly realized how weird this all looked, standing in his bedroom, carrying on a conversation with a dwarf, which just a few minutes ago he thought was just fantasy.
"Okay, you saw me," the dwarf said. "I'm outta here."
"Wait," Jon said. "Where are you going?"
"Home."
"Can I come with you?"
"Humans aren't allowed."
"What if I make myself like you? I have this stone. It'll allow me to become a dwarf."
The dwarf stopped and thought about it. "Okay. But when we get there, don't tell anyone you're actually a human."
Jon smiled and clutched the wishing stone. "I wish I was a dwarf, until I return to this room." It was a good thing Jon remembered to add a limit to his wish. He didn't want to be a dwarf forever.
The stone glowed, granting his wish.
