“Jab with your left and punch with your right,” Dad said, demonstrating with his fists in the air. “Move your head back and forth so it isn’t an easy target. You want to keep your opponent off balance.” For two weeks, the lessons continued daily in the backyard while Sam looked on, laughing most of the time. I grew more confident, trotting to my right, swinging at Dad’s palms. My blows were getting more accurate, making him smile and nod.
