I think that as a kid, she was oK with living in the country, because as a child one tends to accept whatever life one has, as normal. So she accepted the shooting parties at her fathers estate and the spending school hols in the country.. but she never got that fond of riding or took to hunting or shooting..
Im not sure about gardening which is often an amusement for upper class women. Did she like that as a kid?
But I think when she got to her late teens and began to live in London, she preferred it there. and when she began to go for sunny holidays abroad, where she could swim and water ski and sunbathe, she preferred that to tramping across muddy acres in Scotland or England, or watching Charles fishing or listening to the RF gabbing on about hunting and how many birds they shot. but it was expected of her then.. that all Royals spent some time in balmoral or Sandrignham and if they didn't enjoy country sports, they put up with it. But Diana began to gt upset that Charles was out enjoying himself while she was stuck in the castle looking out at the rain..
