If the model realized at scale repeatedly results in the same or similar effects, maybe there is something wrong with the model.
(Be those inherent mechanical flaws, flaws of ignoring parts of human nature, flaws of a model designed to work in a vacuum, or flaws of intricate and fragile necessary rules)
You gave a perfectly reasonable answer to the question in eight words. No evasion.

Not an ideal in forming relationships. Honestly, as much of a train wreck as his response was, at least it gave some useful information to the person he would potentially be dating.
You’ve presumably had conversations with your wife, though, where you shared, and she wasn’t into it. I dunno, at the least you were, perhaps, honest about not wanting to (or not being comfortable with) sharing.
Furthermore, it’s a song and she asked. No one is being subjected to anything. No one has to listen to the song named, or, if they do, even finish the song.
They also say to do what you love, and you’ll never work a day in your life. They say lots of things, many of them contradictory.
I think your advice of intentionally setting aside time is wise, though. I believe that too often we take for granted that things will just happen, and also overestimate the chilling effect of “not being spontaneous”.
