When I was in my first year of college, I    (feel) hopeless, lonely and very depressed.    a cloudy day of September 15, I was walking from class across campus to catch my bus home, head down, fighting tears of despair, when    old man came along the sidewalk toward me. I had never seen him before. Embarrassed at being seen in such an unhappy mood, I turned my head away and tried to hurry past. I thought he would walk on by,    he moved until he was directly in front of me, waited, and then smiled.
 (look) into my eyes, this stranger spoke in a quiet voice, " I’m sure that is unhappy will pass. You're going to be OK. Come on!" I cannot explain the effect of that moment. He gave me one thing I had lost  (complete): hope. I looked for him on campus to thank him, but never saw   again.
That was thirty years ago. I know how lucky  is to meet such a kind man. Furthermore, I have never forgotten that moment,    taught me to give hope to others wherever I see them in trouble.
