Just to continue the analogy about carpentry / home construction. About a decade ago when I moved into my apartment it came with a wall mount for the TV that had a tricky mechanism that would not be clear to a casual user how to mount/unmount from quick looking. And it would be even more difficult to figure out with a TV in the way. 10 years later, it's time for me to move out, and I'd left the TV as the last thing because I had forgotten how to work the mechanism to get the TV off the wall (and it would require all sorts of annoying face-against-the-wall maneuvering to see how to unscrew, etc). I look from the floor up behind the back, and what do you know -- I'd left myself a taped note, extra bolts, and instructions on exactly where to turn the hidden lock screws (in the state where the TV already mounted) to release the unit from the wall. I was marveling at my foresight for a self-satisfied minute (and thanking my past self).
