. . . If you can't understand what send and end mean, you have no business going anywhere near any form of technology invented in the last 100 years . . .
I'm starting to see more of this. A few years back, even the simplest of power tools - drill, hedge trimmers, weed wacker, etc. - came with an instruction manual that would probably take 20 minutes to get through, if you didn't simply do like most people and throw it in a drawer and then just plug in and use the gizmo without any further thought.
I just bought a mini-lathe, and the setup instructions were, well, sparse.
And then I realized, if you CAN'T figure out the basics from that, you have NO business using a lathe.
