i'm with CHLChis on this as i do the same thing. anytime a new firearm is bought or traded, we spend some time getting her familar with it after i am familar with it. we both then spend some time shooting it and getting comfortable with using it. my wife is no where near the gun enthusiast i am, but she does now how to load, reload and operate just about any firearm that i own.
both of them are idiots, but he's a jerk for the way he went about teaching a lesson.
