Need to vent wth is wrong with ppl

I "had" a friend that i would sell a part to every so often if he asked if i had it in the garage.
When i sold him an item,
i then saw it advertised on ebay for three times the price that i sold it to him for.
Then that got me pissed off, him profiting on what i sold it to him for.
When i was diagnosed with a potentially life ending illness you think it would have been nice of him to come up to me and ask, if i can help you sell your parts, and get full market value for them?
But no, he was one of the vultures, and piranhas, circling the driveway, waiting for me to die.
Well, i'm still standing, and haven't conked out yet.
I'm so pissed off towards humanity, that when i conk out, i told the executor of my estate to take a sledge hammer to whatever i have left, and bring it all down to Schnitzers Steel as scrap metal.
Nobody's going to get anything, as that's the way that i feel about it all, profiting from me at an estate sale after i'm gone.
My rant over.
