Life turned upside down

Nick was on his way home from his tiring work when he found a medalion on the street. Somehow he thought it looks nice so he took it and slipped it over his head. Few steps later he instantly changed into a teenage girl, even his clothes matched his body, instead of his t-shirt and jeans he was now dressed in a sleeveless blouse and a loose short skirt. Terrified of what had just happened he ran home.
