I would ask her if she is living as in alive. Of course, she will answer yes. If not, then she has a big problem. Then I would tell her to read Ecclesiastes 9:5 out loud. Then ask her what the condition of the dead is according to scripture. And then ask her what the condition of the living is according to scripture. That should tell her that not only are you aware that you will die, but that she is too.

9:5 NWT 5 For the living are conscious that they will die; but as for the dead, they are conscious of nothing at all, neither do they anymore have wages, because the remembrance of them has been forgotten.
