When I was in retail audio many years ago, I was invited by a teacher to do just that. Set up a good basic system, turntable, receiver, loudspeakers, explained the basics of how it worked and what mattered, and listened to some music. Though they liked it when I played a cut from The Wall, only a couple of the kids (out of 30 or so) were interested enough to ask me any questions afterward. Maybe they continued in the hobby.
I think that is a reasonable (or very generous) expectation of the general public's interest in this hobby. (1 person out of 250 might be more realistic)
My own extended family, though always "hearing" music, doesn't actively listen to it. Only at meets with other audiophools does one really share the music, fun, and continued discovery.
