Why are other people playing my harp so much now?

couple with guitar
young man from Golan

I'm trying tp let other people play my harp more because of pain in my arm from playing too much.I have fibromyalgia, so if you see other people playing a lot you know why.
There was an Israeli couple with a guitar, they both played guitar and so I let both of them play on my harp. It was nice what they did. I believe they now have harp fever, something people get when they play on a harp, and then they start dreaming about harps
A nice young man from the Golan also played. He did not have so much musical training. It seemed to have touched him very much to play on the harp.
