When I was little, I thought that people turned into the opposite gender when they grew up. I have no idea where that comes from.
I also thought that my face was horribly disfigured, like that of a housefly, and that my parents had bought special mirrors that changed what my face looked like, and they paid everyone off to not tell me that my face was weird.
