I really don't think you need to have "a talk" with the other lady. They struck their bargain so let it go.
You got your "deals" and everyone was happy.
When my time comes to past. My husband will do with my things as he sees fit. Whether it goes to the kids or a charity. He can even sell it all if he wishes and divvy the monies up between the kids. Same thing with my truck, it will go to one of the kids who needs it the most.
