she grew up in a farming household surrounded by men who habitually went off shooting game like any other adolescent growing up in a certain environment she would have picked up the basics. It's common sense and she went on shooting holidays and knew how to handle a gun
Growing up with doesn't constitute joining in with. My friend's daughter lives on the farm owned and run by her grandparents, her late father, and now her brother. She has NEVER held a gun, neither, incidentally, has her son who lived with his grandparents until he was eight. These are generational farming people. Sheila was not. Another friend regularly went on shoots with her late husband. She once, very reluctantly, held a gun. She wouldn't have a clue how to load one.
