When I was growing up, one of my favorite television shows was Happy Days, and my favorite character on that show was Arthur Herbert Fonzarelli — or “The Fonz” — who was the epitome of cool. He could tap a vending machine, and free sodas would appear. He could change music on a jukebox just by snapping his fingers.

He could seemingly do anything — well, except for one thing. He couldn’t admit he was wrong. He’d stammer, clench his fist. “I’m wrrrrr,” he’d say, literally unable to utter the words. From the perspective of the show, it was hilarious, but for anyone who struggles to apologize in real life, it can cause real conflict, especially in the workplace.
