“While playing soccer, my friend fell and scraped his knee, leaving a small wound that needed to be cleaned. The coach quickly bandaged it so he could keep walking. Later that evening, at home, I wound the handle of a toy car, and it sped across the floor until it hit the wall. A few minutes later, my sister carefully wound a ball of yarn into a neat circle for her knitting. As night came, the clock in our living room had to be wound to keep ticking.”
