Are you sure there is an 'issue' to 'confront'?
The shoes analogy sounded spot-on to me.
My wife was pretty supportive, (she actually persuaded me to keep on going when I had decided I would never learn to flare), but she has never been especially interested in the details.
If there is a safety concern, buy her a trial lesson. Once I got the PPL, I did that before I took my wife up. I wanted her to see what a 'proper pilot' did before she climbed in with me and assumed I was doing it all wrong. (And all right, yes, I did think I might let somebody else find out whether she would get air-sick
)
