“Hey Ref! You’re making calls out of your aaass!” the father of a nine-year-old kid in a game I was officiating yelled at me at the top of his lungs, adding a two-handed, open-palm slam against the glass for emphasis.

Handing off the puck to my officiating partner, I skated to my designated position, which happened to be a spot on the ice fairly close to where that parent stood, still pressed against the glass. Slowly, deliberately, I leaned forward with my hands on my knees, focusing on the impending puck-drop—and giving that parent a good look at the region from which my calls were coming.
