This is all too true:

... it's getting very costly to live this way. Ironic, to do all yourself on a nice piece of property will take all the money you have.

To have land, to own a house, a home - this is something many of take for granted.
And to have a LAKE - a home on a lake!
To swim every day as your aunt did, up until age 90 - did she really? In New York state? Did she have an indoor pool too?

What a woman!

If we live on in spirit, I'm calling on Aunt Jane.

All you beautiful souls who've gone before us: come live in me, dwell in me, or hey, just hang out with me a few minutes each day. Can you smell the lilacs and see dew drops glistening in the morning sun, if you pop in for a visit with me?

Do I sound like I'm coming unhinged?

My dad's demise has been long and oh, so drawn out, but this week, he seems to be on his way out of this life, perhaps sooner rather than later; and even though he was about as lovable as your spinster aunt, even if he was sometimes not a kind or gentle father, he was MY dad, and there will be weeping and gnashing of teeth and my heart will ache for this man.
I hope your aunt stayed mostly intact until the end. You mention hospice. (Cancer?)
Dad has leg ulcers (who knew such a thing existed) that leak...
Oh the indignity of old age!
Your Minotaur story (prompt: the rowboat was leaking) - the woman on the boat feeling her age - oh man.

We are not living longer, these days. We are taking longer to die. --Andy Luck
