Hell, I've got two cans of R12 still sitting around. Can't bring myself to dispose of them (my "illness rearing its ugly head again.) And they'll probably be sitting on their shelf when I pass away.
Is that as much to say that you have a "Hoarder's obsessive compulsion"?
That would make for a refreshing turn on the cable-TV series "Hoarders". Somebody who hoards automotive crap.
I was cured of my habit when I moved out of my condominium unit 20 years ago. I was loading my U-Haul for the trip west. I had a caged storage unit in the building basement, which I had filled with old transaxles, a Honda engine, brake and wheel parts, carburetors, etc. -- all sorts of grungy s***. In the distraction of my moving activities, I lost track of the storage unit's status, and left half of the junkyard trash behind with the door open. I was later made to pay a fine for the mess I left.
I'm starting to do this sort of thing again -- acquiring parts for my 25-year-old SUV. I must be stopped!
