Once outside of the classroom, Jon's eyes went wide. He spun around and looked back into the room he had just left. Everyone in the class was now a girl. Even the teacher!
He looked down at the stone that was in his hand. This thing was trouble. He had to figure out some way of getting his stone back. He knew that he could probably wish it back using this stone, but with the delay, would that be wise?
Suddenly, the school bell rang, signifying that first period was over. And all the girls from the classroom began walking out. They didn't even seem to notice that anything was different, but that was probably because they didn't hear the wish. Jon cursed to himself, realizing that at least twelve of the girls used to be guys and now they had no memories of it.
Jon was so shaken up by what had happened that, when one of the girls (one of the new girls, more specifically) bumped into him, he lost his grip on the stone and it fell and slid across the floor. With all the people walking around, he had no idea where it was.
He cursed to himself again.
