It was true, Keisha couldn't reverse wishes. But maybe perhaps she could redefine them? Like be more specific? After all, this wasn't what she meant when she made that last wish.
So with that, she clenched the stone and said "I wish that when I said 'people like me who understood what it was like to be me', I meant that the people would be similar to me but not exact, and that the people would have similar experiences, knowledge, likes and dislikes as me, but not be exactly like me."
She hoped that that would work, and a second later, she realized that it had. All the people she saw were black girls, but they only seemed somewhat like herself, wearing fashion that Keisha favored, but not the same exact outfit, and going by names other than Keisha's own.
Keisha looked at the election posters and saw that all five of them were still for black girls, but they all looked noticeably different from one another. And they all had different names.
A voice spoke up from behind her, calling out her name, but for a moment, she didn't notice. After all, just a minute ago, everyone was calling each other by that name. It was only when a hand grabbed her shoulder and turned her around that Keisha realized that someone was talking to her.
