I wandered in the park. The park bench was___21___ as I sat down to read beneath the long, straggly (蔓延的) branches of an old willow tree. I was disappointed by life with ___22___ reason to frown, for the world was intent on dragging me down. ___23___ that weren't enough to ruin my day, a young boy out of ___24___ approached me, all tired from play. He stood right before me and said with great excitement, "Look what I found!" In his hand was a flower, and what a ___25___ sight, with its petals(花瓣) all worn --- not enough rain, or too little light. I faked a small ___26___, wanting him to take his dead flower and leave, and then ___27___.

How did he ___35___ my difficult situation? ___36___ from his heart, he'd been blessed with true ___37___. At last I could see, ___38___ the eyes of a blind child, the problem was not with the ___39___; the problem was me. And for all of those times I myself had been ___40___, I vowed(发誓) to see beauty, and appreciate every second that's mine. I held that wilted(枯萎) flower up to my nose and breathed in the fragrance of a beautiful rose and smiled as that young boy.
