I was raised with three non-biological elder siblings. I wish I could tell you they meant well. They didn't.
Harold, the biological father of myself and Brad, purchased a number of cemetery plots in Kzoo.

The number was calculated to include my then extant mother.
Almost a century later, Brad was in hospice. He'd refused sustenance. His home care was managed by a person, Shiela Koringiebel McKay-Vaughan, whom I could think of as my third mother. That is how sincerely she had

Brad's, and my, best interests at heart.
My best "educated" sister would often berate me for not telling the entire truth.

Absolutely. That makes perfect sense. A Washington state Realtor is the obvious choice to sell a Florida home. How else might we prolong our Father's agony?
When Brad was in hospice

at least two of the three got the idea that this was a financial opportunity to undermine Our Father's agreement to bequeath his entire remaining estate to my third mother. Brad, at that time, had less than five figures left. Maybe 4. If that. Sisters thought that if they could get His care transferred to them, they might alter the bequest.

In Japanese, one does one's own headaches. How are your migraines now?
In His Will, he was very clear. He wished no funeral, no fuss made. Even more clearly, and protected by law, was His dispensation to my third mother. After his purported passing

I asked Chris (aka CJ)

if I could test Brad's DNA. I told her, on the phone, I wanted to know if he was my biological father. She replied,
I am sure he's my father.
Odd. I'd never asserted he was not her father. As Brad often used to say
Me thinks thou doth protest too much.
He had made CJ the executrix. She was taking her responsibility seriously, as she does. She flat out refused we test Brad's DNA. His body was to be donated to "science"

as had our mother's supposedly...until I met her a few kilometres from my home in NSB.
I suggested that he be buried in one of the open plots in ZooKingdom. Again, not even gonna discuss it. I knew suggesting a memorial service was wasted breath. Firstly, he had literally no friends in the area at the end. Some years back, Burmese friends had bought him a mobile home on an island in the inland waterway under a bridge

which We helped build.
