Things change. Generations dilute traditions and societal norms change tastes in activities and morals.
My daughters interest in guns ranges from passive to nonexistent. There is really no point in passing any of my guns on to them, but they will each get a couple. What they do with them is of no concern to me. It used to be, but as I said, things changes.
If I were to turn the tables and see what I would inherit from them, I would have no interest in anything they own at this time.
Completely understandable that they would likewise have little interest in what I have in the way of firearms.
