"How do I look?" she asked Jon, turning towards him.
"You look ... like a Goth."
She smiled.
Then Jon said "In fact, you are a Goth. And this is your bedroom."
Suddenly, his mom's demeanor changed. "Of course, it's my fucking room. Now get out, twerp!"
After she nearly slammed the door in his face, Jon heard metal music blasting from inside the room.
"She actually thinks she's a Goth," Jon whispered to himself. "She actually believes it, as though she was always one."
After a few minutes had passed, Jon decided that he had taken this test too far. It was time to get his mom back to normal.
He knocked on the door, repeatedly. After about twenty knocks, the door finally flew open. "Why the fuck are you bothering me?" Jon was nearly knocked down. First, because of the way she talked, and second because she looked different. She still wore the Goth clothes he saw her in before, but now she also had black lipstick and eyeliner. She must have put it on after she threw him out of the room.
"You're not a Goth! You just want to see what it would be like to be one."
Her demeanor changed back to normal. "Well, of course, Jon. Just because I put on one of Zoe's outfits and put on her make-up doesn't mean I want to be a Goth. It's not like I pierced my nose or got a tattoo or something." She walked back into the room and turned off the metal music. Jon turned his back, as his mom took off Zoe's outfit and put her normal clothes back on.
"What about the lipstick?" Jon asked.
"I can remove that." Then she left Zoe's bedroom, leaving Jon to reflect on what just happened. His words had real power. He didn't just have the ability to change people's minds about things. He also had the ability to change their memories. And that was a dangerous thing.
