Yeah, I worry about parts a lot. The unit I'm using now was built from what was on the shelf at Princess Auto, so it's no problem.
Today I was up to ankles in mud...new area of town, no grass, two days of rain, but they want it finished because they never bothered to train their dog. I got the auger stuck in the clay.
So I've got 4x4's under the Jack-All and under the axles, and it's just the kind of mess that you can only get yourself into by saying yes when you should have said no. What the heck though, it's not like I had anything else to do today.
The kid walks out (he's maybe 16 and less trained than the dog) and says, "You sure work hard."
"That's what happens if you don't go to school," I said. Which is more or less true, I guess. I know quite a few university graduates, and not one of them was standing there in the mud with me.
Anyway, a while later his mother comes out and hands me a beer and says, "Thank you. I heard what you said and he needed to hear that."
I'm kind of ambivalent about that. I hate to see some innocent kid trapped into a life of wearing a tie and spending his life under florescent lights. On the other hand, I got a free beer.
