Mary was talking about her hair.
Mary: Old women shouldn't have long hair. Maybe I'll get a SHE-no.
Me: A what?
Mary: Well, how would you pronounce it?
Me: Pronounce what?
Mary: C-H-I-G-N-O-N
Me: You'd be surprised how many hair words I don't know.
Mary: You know a chignon. It's like the Gibson Girls.
Me: Gibson Girls.
Mary: A series of paintings in the 1800s. All the girls have this hair.
Me: That's a good plan. If I'm unsure, give me an art reference to hang my hat on.
Mary: Exactly! A hat would hang on a chignon.
