Facebook says so
Facebook says so is like having a dictionary that only knows one word. You're stuck with whatever Facebook says you are.
My profile says I'm a 'bored teenager' even though I'm 30 and work 80 hours a week.
My friend's page says she's a 'famous singer' even though she sings in the shower.
My dog's bio says he's a 'legendary detective' because he barked at the mailman.
