求一篇英语作文,第一次见到陌生人,尽量用点高级词汇!

One day, I spotted an old man in the street. He was in his sixties, carrying a big plastic bag with a couple of bottles in it. Therefore, i walked up to him without hesitation, and i spoke to him politely, "Sir, would you like me to carry the heavy bag for you? ", he looked at me with a big smile, "Oh, my boy, thank you for your kindness." Then, we walked together towards his house, and we became good friends.
