“The sooner the better, before she burns through what’s left of her savings.”
Nope—she’s gone through her savings—but she doesn’t seem to be at peace in the least. What quality of life do you think a 93 yr old has on dialysis and chemo. For the last 20 years she has been unwilling to do anything but watch TV and do crosswords.
I don't know, why don't you ask her, instead of putting a pillow over her face?
Your indignation at her inconvenient "bitter clinging" to life is pretty self-evident. Gut-check time.
