What is cultured? Me and my friend disagree. A joint friend of ours is 40 this year and never been out of the Uk although she goes back up to Scotland to visit family and possibly been to Wales. She has zero interest in foreign travel.
She is fun, reads widely and extremely knowledgable , knows every flower and plant, sporty, can hold a conversation about anything, loves theatre/museums etc
My other friend thinks she is not very cultured as she has not been abroad??
She can have a conversation about anything and is one of the happiest people I know. I don't see not travelling as lack of culture!
