Wish Chain: Amber Is Melissa?

"Well, I wish everyone would think I'm *Melissa*," Biff said. This was Biff's second wish, so it was granted to the person who was closest to him, which was Amber. Everyone surrounding Amber got a glazed look in their eyes and then blinked. "Melissa, shouldn't we get going?" Jessica asked. "I want to make sure we get to the mall in time." "Why are you looking at *me*?" Amber asked. "*She's* Melissa," she said, pointing at Melissa. "No, *you're* Melissa." "What's wrong with you? I'm Amber, remember?" "No, you're Melissa. I've been friends with you for years. Don't you think I'd know what your name is?" "She's right, Melissa," Randy said to Amber. "What's going on? Why are all of you acting like this?" They all looked at each other. "Acting like what?" Jessica asked. "Well, first Melissa lost her memory, then Biff thought that *he* was Melissa and now everyone thinks that *I'm* Melissa." "You are," Mike pointed out. Amber glared at him. "My *name* is Amber." "If you say so," Mike said. She looked around at all of them. They really did believe that her name was Melissa. They weren't playing around. What was happening?
