You've been debugging for THREE HOURS, your eyes are bloodshot, your coffee's gone cold, and you're questioning every life choice that led you to this moment. Then FINALLY—like finding water in the desert—you discover it's a rogue whitespace character. A space. A tab. Some invisible demon lurking in your code like it owns the place. And just when you think you've won the battle, you realize... wait. There might be MORE of these invisible gremlins hiding elsewhere in your codebase. But do you have the energy to hunt them all down? NOPE. Not today, Satan. You fix the one causing the error and pretend the others don't exist. What they don't know won't hurt them, right? Right?!
