Running late again, I rushed into the Cub Scouts parents meeting, noting the surplus of em

pty chairs. At least, I wasn t the only one running behind, I told myself with great relief. The Cubmaster checked his watch, and with a barely audible sigh, started the meeting. As the Cubmaster explained the challenges that the group faced in the coming year, he pointed out that the empty chairs, which should have been filled with parent volunteers, were our biggest obstacles. As he spoke, I felt a rising sense of guilt mounting within me. Wasnt I looking forward to leaving my seven-year-old in the care of a competent adult while I ran errands？ I quickly came to realize that the problem wasn t just about empty chairs: it was also about people like me who were unwilling to sacrifice some of their time to a worthy cause. Before I could change my mind, I raised my hand to volunteer as den (幼年童子军小队)leader. Although I knew next to nothing about teaching a group of noisy and restless second-graders, I was determined to make it work. My first den meeting was as chaotic and noisy as the first day of a county fair. The boys were too excited to sit still. What have I gotten myself into？ I wondered, composing a letter of resignation in my head. Much to my surprise, the boys actually enjoyed themselves. They even invited their friends to join our den, and before long, our ranks swelled from four boys to ten. My son was thrilled to have his mom as den leader: it gave him bragging rights on the playground. As I walked through the school s parking lot, it was rare when one of "my" boys didn t call out a greeting or stop me for a quick hug and a story to share. They would talk with me about the little things going on in their lives—whether it was a loose tooth ready to wiggle its way out or a special event coming up. As I watched them, I thought of the empty chairs at that meeting and those who would never know this joy. After all, I gave those boys only one hour of my time every week, but they rewarded me with their hearts.
