Discworld

What I do remember is fucking sobbing in my bathtub because of how obvious Pratchett made it that he was aware his time was coming and he wanted to face his own mortality, and did so by taking Granny Weatherwax with him.

For those who don't know Pratchett was diagnosed with Alzheimer's eight years before he died, and advocated for the legalization of medically assisted suicide. He was open about how he struggled with Alzheimer's, and how he wanted to die while he was still himself.

I don't remember the plot of the book, but I do remember Granny Weatherwax cleaning her home, taking a bath and dressing in her finest clothes, then altering her "I ATE'NT DEAD" sign to say "I IS PROBLY DEAD" before laying down to pass away.

I remember Death greeting her with a kind judgement when he came to reap her soul.

FOR I CAN SEE THE BALANCE AND YOU HAVE LEFT THE WORLD MUCH BETTER THAN YOU FOUND IT, AND IF YOU ASK ME, said Death, NOBODY COULD DO ANY BETTER THAN THAT.

"That's why [magic] was left to wizards, who knew how to handle it safely. Not doing any magic at all was the chief task of wizards—not "not doing magic" because they couldn't do magic, but not doing magic when they could do and didn't. Any ignorant fool can fail to turn someone else into a frog. You have to be clever to refrain from doing it when you knew how easy it was. There were places in the world commemorating those times when wizards hadn't been quite as clever as that, and on many of them the grass would never grow again."

And I'm like...that sounds familiar...only as William de Worde, which is of course this guy

The reason that Granny Weatherwax was a better witch than Magrat was that she knew that in witchcraft it didn't matter a damn which one it was, or even if it was a piece of grass.

The reason Magrat was a better doctor than Granny was that she thought it did.
