Jon looked down at himself and saw that he was wearing feminine clothing, even though he was still a guy! It must have been a personality swap that happened.
"Oh god, what happened to me?!" he heard his mother yell. He looked up and saw her standing just a few feet from him. She looked quite a bit more tomboyish. T-shirt, jeans, sneakers. All of her make-up was gone and her hair was considerably shorter, mimicking the haircut of the typical high school boy.
"Mom, please keep your voice down," Jon said, as gently as he could. It was odd, but he felt a kind of motherly love for her. It must have been because of the swap.
"How is this possible?" Jane asked, settling down, but still freaked out.
Jon didn't bother giving her an explanation. Instead, he reached out and grabbed her hand and said "Swap."
