When I was a senior in high school, I went on a skiing trip with some friends. One day while we were sitting around the ski lounge, a boy and a girl no older than six years old were playing behind us running back and forth down a corridor. I was in no mood for it and told my friends, “if they pass us one more time I’m going to yell at them.” And they did. So I did. As the boy was passing behind my chair, I turned and shouted “HOW ARE YA!!” so loudly and level with his face that he was actually thrown off his feet in mid-stride and hit his head against the far wall. It looked like he had just run full-steam into a punching bag and glanced off it diagonally. I was really pleased with myself but hoped his parents weren’t around to witness it.
