GRANNY IS A SOPHISTICATED WOMAN

Granny doesn't seem to think the descriptive "sophisticated" fits her. Perhaps not, in the common usage -or misusage- of the word. But according to my Noah Websters, the school edition I keep on my desk and the 10 lb. wrist breaker that resides in my secretary, the description fits her admirably.
Ofcourse, English being a complex language, a living language ever evolving and a mish mash of various other languages, Old Noah is forced to give a number of definitions to words at times. But....

School edition: sophisticate, v; to make less natural or simple; to alter, as a person, by education or experience; to increase the complexity of; refine. n.; one who is sophisticated.
sophisticated; changed from the natural character or simplicity by education or experience; appreciated by or indentified with intellectuals or sophisticates; worldly-wise; subtle; cultivated; intricate or complex.

I think that by "less natural or simple" this definition is described in the next phase - become more complex, refined, cultivated and world wise through education and experience. You may still be an all-natural person but you are a far cry from the simple child or youth you once were. You are an educated, experienced woman, a complex person, and wise in the ways of the world.

And by this definition, you are a sophisticated woman and take that ignorant man's misplaced "put down" as a compliment. It isn't your fault he is too ignorant to understand the word he used. And sophistication has nothing to do with socio-economic status nor wardrobe. I've known some very wealthy people who, by Noah's definition, were lowly clods.
