A voice was audible from the hallway. "PAMELA!!"
"That's your mom," said Pam. "But why is she calling me?"
Just as Pam asked her question, Zoe knew what had happened. They had exchanged families. Pam was now part of her family and Zoe was part of Pam's.
"We have to fix this," Zoe said. "I want stay with my family."
The door opened and Zoe's mom (now Pam's mom) stepped inside. "Pamela, you better tell your friend to go. We're eating dinner."
