Jon looked down at himself and saw that he was older! It must have been an age swap that happened.
"Oh my god, what happened to me?!" he heard his mom yell. The pitch of her voice seemed higher. He looked up at her and saw a teenage girl. He had seen pictures of his mom when she was in high school and that's exactly how she looked now ... except for the contemporary look. Jon was sure that her high school would never have allowed her to wear something that revealing.
"Mom, listen to me. It's okay," Jon said. It was so weird hearing his deeper voice. How old was he now? Thirty-seven?
"Jon, just tell me what's going on," she said, settling down, but still clearly freaked out.
Jon didn't bother giving her an explanation. He reached out and touched Jane's hand and said "Swap."
