Eventually

No one at school ever talked to Ruth. The kids all knew her family was extremely religious, and she dressed in outfits that seemed centuries out of date. However, no one at school could have anticipated her plan. Conducting an ancient ritual in secret, she managed to swapped bodies with a moderately popular boy named Jake. He was terrified to wake up in Ruth's house in HER BODY! The phone rang, and it was his old voice. It was Ruth explaining that she was sorry, but she thought that maybe Jake could stand up to her conservative parents for her, and that if he did so she might consider swapping them back...eventually.
