The First Rule Of Programming: If It Works Don't Touch It

You know that code you wrote three years ago that somehow still works despite violating every design pattern known to humanity? The one held together by duct tape, prayers, and a single if-statement that nobody understands? Yeah, that's the cow standing on a tiny stool.

Every developer has encountered this sacred law: the code is functional but the architecture is... questionable. You want to refactor it. You should refactor it. But deep down you know that touching it means spending the next two weeks debugging why the entire system collapsed because you changed a variable name.

So you leave it alone. You document nothing. You move on. And when the new junior dev asks "why is it built like this?" you simply whisper: "We don't talk about the cow."
