when you're trying to open something and your fingernail breaks instead of peeling the seal

You spend three minutes working your nail into the corner of a sealed package like you're defusing a bomb, feel that perfect little grip, apply pressure with the confidence of someone who's done this before—and snap. Now you're bleeding slightly, the seal is still intact, and you're standing there holding a broken nail like evidence at a crime scene while the scissors sit in a drawer you refuse to walk to on principle.
