My Mom was VEHEMENTLY anti-gun for many years, somewhat surprising since her parents both carried and used firearms frequently. She didn't have a problem with Dad and I owning or using ours, but she simply refused to have anything to do with us when we did.
About two years ago, we took our various .22s on a camping trip and were having a blast plinking away. Mom was apparently bored and came down to watch us. An hour later, she asked us to show her how to shoot, so we started her out with a Remington 514, then my Wifama, then a Glenfield 60, then a 10/22...now she has her "own" Glenfield with a 4x20 pencil scope that she drops starlings with, and has been bugging me to let her "play" with my Garand.
