Good for you! Here’s the next step – you’ll notice him humming one of your tunes.
The ultimate though, is when you get, “What was that last tune called?”
When I started learning bagpipes I used the practice chanter, which sounds kind of like a cross between a kazoo and a duck. My wife used to complain about it. Then I started playing the highland bagpipes and she no longer complains about the practice chanter.
The moral of this story is that if one’s spouse complains about a little tin-whistle, the solution is to learn great highland bagpipes. Either that, or drums!
