> You'd probably get the same question from a plumber if you asked him how to plug a pipe in a non-intuitive way. He has no way to know your pipes are laid out in a strange way, and the only spot you have left to add said junction without redoing your plumbing is back there - unless you tell him.

Sure, but if I told a plumber they'd understand and help me find a solution to my problem. That isn't what happens on StackOverflow, instead they try to convince you that you have to change your problem to fit the solutions they're familiar with.
