My older sister told me that at the age of 16 girls turned into boys and boys turned into girls. I was so mad that I had been born a girl because that meant I wouldn't get to wear makeup or wear prom dresses when I grew up (because by then I would be a boy).
A childhood belief about getting older

others believed things like this
- That boys turned into women when they became adults and girls turned into men when they became adults. Anon
- I used to believe that little boys grew up to be girls and little girls grew up to be boys. — Darin
- When I was a little girl, I believed that all cats were girls and all dogs were boys. :)— Mary Ellen
- I thought that the difference between girls and boys was that girls have teeth.
Anon - when I was a kid, I used to believe that only girls could be my friends and all other boys were my brothers.
