Meredith (opening voiceover): My mother used to say this about residency, “It takes a year to learn how to cut. It takes a lifetime to learn not to.” Of all of the tools on the surgical tray, sound judgment is the trickiest one to master. And without it, we’re all just toddlers running around with ten blades.

    Meredith (closing voiceover): We’re human. We make mistakes. We misestimate. We call it wrong. But when a surgeon makes a bad judgment call, it’s not as simple. People get hurt. They bleed. So we struggle over every stitch. We agonize over every suture because the snap judgments, the ones that comes to us quickly and easily without hesitation, they’re the one that haunts us forever.
