Not who she appears

"Wha... How do you know about the medallion" George stammered.
"How do you think?" The woman sitting across from him replied, "I've used it. Think about it, how many people have you seen this small?" she asked in an annoyed voice.
"But, why?" George asked, "Why did you make yourself so small to begin with?"
"Well", the woman replied, looking a little ashamed of herself, "I did it for my boyfriend at the time. He was a college football player and I was a 30 year old professor. I fell in love with him but I knew we could never be together. Then one day, I came across the medallion. I showed it to him and we were so happy to be able to be together, at first the plan was to make myself a normal sized girl but then one of their cheerleaders had an accident and had to leave the team. She was the position that gets thrown in all the cheers, the flyer."
"So, you became her?" George asked.
"No, her accident was public knowledge and no one would believe she recovered so quickly so we went about putting together an outfit that would change me as needed. You see, you can change youself in any way you want as long as you put the clothes on at the same time. My boyfriend was very full of team spirit and wanted the team to have a cheerleader everyone would remember so he suggested we make myself around four feet tall. At first I refused, I said the lowest I would go is five feet. He agreed and we assembled the outfit that would change me, I put my affairs in order, and went to his apartment to make the change. Little did I know that after he left he went to a tailor and had everything scaled down to make me this small. Of course, he kept the breasts big, typical man", at that she waved her arms down her body.
"That's awful! Why didn't you just wait 12 hours and change back?" George wondered.
"I was going to but he convinced me to stick with it, 'just for a little while', was how he put it. Whether I agreed or not, it didn't matter, he had already gotten rid of the medallion, which I didn't find out until later. So anyway, a couple of years went by and things were going very good for us. He was on his way to the NFL and I was the number one cheerleader in the state. It turned out that this body is extremely athletic, which made me able to do some things most people could only dream of. But then one day, I came home from practice to find him in bed with another member of my squad", she paused to wipe tears from her eyes at this.
"I'm sorry", George said.
She sniffled and continued, "Needless to say I was pissed. I gathered up all my things, including some of his, and left. I just drove and drove, not knowing where to go or what to do. I finally ended up here where I sold his clothes and managed to get a job as an aerobics instructor. It's not what I'm used to and the pay is nowhere near what I used to make but the person I am now doesn't have any kind of education or experience."
"Wait, when you say you sold his clothes, did you return some to a store as new?" George asked, already knowing the answer.
"As a matter of fact, I did. Just one jersey though, and only I wore it anyway, it was a nightshirt for me... Oh now I get it, you must have bought it thinking it would make you..." She paused, "Wait a minute, were you a man before?" she asked.
At that George's cheeks turned red and he meekly replied, "yes". He felt so small admitting that for some reason.
"I'm so sorry. I never thought the person who would end up with my jersey would be someone with the medallion" she apologized.
"It's ok" George said, and he really meant it. This experience was already better than anything he had ever done in his life and it was only going to get better. He thought of Sarah, and what she had planned for tonight.
"Besides, it's only for 12 hours and I can change back, or at least into someone who can go on the adult rides" they both chuckled at that.
Just then Sarah came into the restaurant. She looked at the people in line and didn't see him so she scanned the tables and saw the other woman. She couldn't see George because he was shorter than the booth seat but the other woman was facing her. She went over and said, "Hey, what made you decide to get a table? And how did you hair get blonde again" as she approached them. When she got there, she looked in the other seat and saw George, his hair still black.
"Whoa, so you must be..." Sarah started but was interrupted by the woman.
"That's right. I'm the original. Please to meet you, my name is Rachel" as she held out her tiny hand. Sarah took it in hers and shook.
"I'm S-Sarah", she said.
"And I'm George, by the way", George added, "But you can call me Tina for now"
