Ah, the classic tale of software development lifecycle. Panel 1: A beautiful, organized tree structure representing clean, modular code. Everyone's happy. Panel 2: The client utters those fatal words about needing a function to do "something in this place." Panel 3: Nuclear explosion. Your pristine architecture doesn't survive first contact with changing requirements. You wrote a masterpiece that handles A through Y perfectly, but the moment someone asks for Z, the whole codebase collapses like a house of cards built by a caffeinated squirrel. And that, kids, is why we drink.
