So when I started my PPL I sallied forth to the pub ready to hold discourse with admiring friends on my joining the brotherhood of bold aviators.
"How do you know there's a pilot in the room?"
"He'll tell you!"
I've been divorced for 10 years as a result of misunderstanding women's attitudes.
I think this is called AIDS - Aviation Induced Divorce Syndrome
But seriously... I think men are bad at multitasking and very good at focusing on one thing for a long time. To the point where a hobby may become an obsession. I have not only seen this in flying, but also in computers (when computers were considered a "hobby") and photography (particularly now that digital is of high-quality and dirt cheap).
Maybe it's not the flying itself that she doesn't understand, maybe it's the obsession with it.
