Nothing unusual about that.
For years I taught classes to civilians, including CCW classes.
It did not take long to figure out that to make things go smoother, that husbands and wives, BFs and GFs needed to be seperated, so the male half would quit "teaching" and showing his "little lady" all the stuff he knew.
The vast majority of men seem to think that they are born with the skill sets to be naturally great drivers, incredible in bed, excellent shots and good fighters. Their ego is very much wrapped up/associated with those things.
What I found (along with a shit load of people who teach firearms related classes) is that women (generally speaking) have no ego wrapped up in dealing with firearms.
Once you discover what their preferred learning method is (auditory, kinesthetic, etc) they actually listen, and apply what you teach them. On an average,when dealing with neophytes, by a considerable margin, it has always been easier to teach women than men to shoot.
Plus I truly think that they have better hand eye coordination.
The female only classes I taught were some of the smoothest classes ever.
The WORST students by far were older men who had been shooting for years. Especially from the generation who grew up with, and used revolvers for years before semi autos became prevalent.
They already know everything (except what a sight picture is actually supposed to look like), don't listen, and absolutely CANNOT keep their finger off the trigger, when their guns are no longer pointed at a target. These "experienced" older male shooters were BY FAR, substantially more dangerous than any other group of shooters.
They stand with their gun pointed somewhere other than the target, with their finger on the trigger.
Perform reloads with their finger on the trigger.
Carry on conversations with others, with their finger on the trigger. Etc, etc.
After one incident with a late 70s, early 80s gent named Harold, who when asked to stop shooting, and please join the rest of the class, turned around and began talking to me with his finger on the trigger of his PPK. The hammer was back, and was pointed directly at my chest, at a range of about a foot. After that was resolved, I started calling all older guys who exhibited the same incredible firearms skills "Harold".
