My grandma keeps talking about her own death now

Kardilian

And it just sucks. I don't want her to die :/

After my uncle died, she's living alone, and she is preparing her home for us so it's nice and clean and free of clutter when she dies.

I'm the morbid one, wtf grandma :,(

Any thoughts on this? I don't know if this is just natural or if I should be concerned.
