"I wish there were twice as many Goths at this school," Zoe said. The stone glowed, granting her wish. Since there were currently six Goths (five girls and one boy), Zoe figured that six more would be added (probably by changing current students into Goths). But instead, it seemed that almost everyone walking around the school grounds was Goth. It looked like a mass of black.
"What the fuck?" Zoe uttered. "That's a hell of a lot more than just six more."
She was right. It was more than just six more, because the stone didn't just double the number of Goths at the school. It multiplied it six times! So now, there thirty-six Goths.
