Who are you talking about?
I'm not pleased with the contradistinction (is this the right word in English?) you suggest.
I love my instrument for the music it let me play. That's what I do at home, with and without people around me.
But I also love my tina for its looks, for its history, for its construction, for its place in its family of instruments.
And I am fond of this community of experts and enthusiasts who share their love for and their knowledge of our concertinas in all its aspects. That's not fretting!
And now I turn off my computer and go and play me a tune.
