I was an NRA Instructor for years and the very first thing I learned about teaching is that some students think they already know more than you - and some realize that they know nothing. The latter made teaching so much easier and produced a far safer shooter and their scores were considerably higher on the first day. All of the women would go to the range with their husbands after the training and completely outshoot them. It was hilarious. Interestingly ALL of the women approached gunhandling fully realizing they knew nothing and wanted to listen and learn and almost all of the guys thought they were Don Johnson and knew everything there was about guns. I loved teaching those women's classes. I could tell some stories.......
You were lucky. I had a women tell me that I couldn't give her orders because she knew what she was doing and wasn't going to doing anything dangerous. Immediate end of lesson.
