This is all a matter of education, to me. Boys don't grow up automatically knowing how to build an engine . Men and women are taught , and later, according to their interests , which society, or traditions also can play a role.
My father , being a vet , pilot, master mechanic and builder ,taught me early on to always be keen for any changes of sounds or "feel" to an engine . Teaching me to fly played a huge role in keeping my trucks well maintained . I hear something off, even a wee bit, I look into it. He would tell me that I was more sensitive to sound, pitch and feel than most guys he flew with. All systems of operations are dutifully cared for right on time . I watch gauges in my truck like a hawk. I fuel up at half tank, always.
Mechanics are worth their weight in gold to me, and I do my part to try and make their time spent as easy as possible.
As far as being on time, for me, merely showing up "on time",is late . Anyone who has experienced me picking them up at an airport can well testify how early I am , an hour at least, waiting right in front of baggage claim exits. I am early for all appointments . My father also had the countenance of being early instilled , from his service in the Navy. Our friends who were vets also viewed timing in similar fashion.
Sometimes the spark of interest in learning something outside of their realm can be accomplished with simply asking them to help you , Wolfie . Like you did with your lady's interest in firearms !
My motto for life...."it doesn't hurt to ask."
