It was a freezing winter night. I pulled myself along the way before a long day's work stand behind the counter. An empty stomach and only ten-dollar note and a few pennies in the pocket, my life seemed hopelessly. Despite the warm Christmas atmosphere, my heart was frozen to dead. “Excuse me, Madam. Would you please be too kind as to give a few pennies? The little angels will appreciate for it.” A sweet voice rise behind me. I turned and found a plain-looking girt with two abandoned dogs. Without hesitations, I handed over the note in my pocket. Cheerfully the girl wait away and she would never know how she saved my day and my life.
