Woman I know has been a SAHM for 25 years but refuses to be called a SAHM and instead claims to be/wants to be called an artist.
Her artistry is more like a hobby that she does every few months. She has built a studio in her backyard to produce art but isn't there much. She has never sold her work, never had a show, never been part of a group show, never had an open house, doesn't have a website. Of course you don't need to do these things to be an artist, but I think producing work is key!
Her DH is part of a sort of posh 'cultural milieu' and I'm sure claiming she's an artist because it's a more acceptable title but come on - can you be an artist if you don't produce art, just like are you a writer if you don't or rarely write or a musician if you don't or haven't produced music?
