My grandmother died a few months ago at 89. I tried to delicately open the subject with her a handful of times over the last 10 years or so, and she immediately shut me down each time. She wanted to die and go see my grandpa. No amount of talk from me would have changed her mind. And it hurts, knowing that I'll never see her again. But sometimes, there's nothing we can do. People will do what they want.
