A childhood belief about general

When I was four or five, I got out of bed one night to join my mother and her friend downstairs. It was very late, so my mother and her friend convinced me that little boys who were awake after midnight turn into girls. Once I was back in bed, I had to keep checking that my privates were still there and my hair was still short. I had no clock in my room, so I was terrified that the stroke of midnight could come at any time and I would become a yucky girl.
