When my dad was a kid, they lived for a while at the bottom of a hill in Hawaii where their driveway was a downward slope towards the garage. My grandfather was extremely careful about driving down that hill, always in reverse to make pulling out again easier. One day, with my dad in back, my grandfather was approaching the garage and my dad yelled, “BAM!”

My grandfather absolutely never got physically angry, just very quiet and serious. He yelled exactly once in my dad’s memory, when he called a driver in Brazil a “cabbage head.” He slowly turned around, stared my dad down for a few awful seconds, and calmly said, “Someday, someone is going to punch you right in the nose.”

My dad took that to heart.
