The outstretched(伸出的) hand caught my eyes immediately. I’d fallen on the sidewalk, having tripped on the curb(路边). A hand was there, ready to help me. Then, warm smile and, “ Are you OK?”
I’d fallen on my hands and knees, and I was fine. But I loved seeing that hand reaching toward me. The woman helped me up, made sure I was all right, and we both went our way.
As I remembered this incident during the next few days, it became a symbol of the significance of helping another one. In the grand scheme of things, such help may often seem small, but at the moment it’s needed, it can feel very significant.
One of my most meaningful lessons on how to help others came at the end of a week-long music workshop. At that final gathering, we each had the opportunity to perform for the other participants. A woman who was  much more experienced and accomplished(技艺高超的)than I ---- a piano teacher who attended the workshop in order to learn new teaching techniques- invited me to play the piano with her. I'd actually been quite happy as part of the audience, watching the other students perform. My piano skills were elementary, and my confidence was low.
When she asked, though, it was almost as if she’d taken me by the hand and led me to the piano. As I plunked out a melody(旋律), she played a lovely accompaniment. Hearing that accompaniment to my melody moved me to tears. She was helping my music be beautiful—helping me play my song. But the lasting impact of that experience related to much more. I took away with me the lesson that we are each here to help one another “ play our songs” --- live our lives to the fullest, be the individuals whom we are.
