Thanks to my dad, for the first 10 years of my life I believed that C.I.D (Criminal Investigation Department) stood for "Constable In Disguise"
A childhood belief about work

others believed things like this
- i used to believe that a volcano was an upside-down UFO in disguise— Sally
- i used to believe that my dog was really a cat in disguise trying to get information on the dog empire!— strange and used to be stupid
- Until I was about 11 or 12 I thought that "prostitute" referred to a female criminal.Anon
- I used to believe that eye-lash curlers were eye-ball eating aliens in disguise— Eliza
- i used to believe (because my dad told me so) that AM stood for "awful music" and FM stood for "fine music"— skydvgrl
- I used to believe that the short display beds at department stores were for dwarfs.— p
