Carol is moody. You have spoilt her holiday plans by suggesting that you go to the countryside. Where she comes from, they hate western Kenya. It is too much work. She wanted to fly to the South Coast. An idea that you dismissed and she has been aggressive ever since.
But Carol is not the first woman to hate the countryside. Many women associate the countryside with backwardness and demanding relatives. And rightly so. You are absolutely sure that Carol will have a difficult time there, but you want her to get used to your family because she will be living with them forever.
