My uncle has a very beautiful umbrella. He’s had it for years. As he is very careful with it, so it still looks as good as new.   1  He shook his head. "Then how did you get it?" I asked. "Well," he answered, "there’ s a strange true story about the umbrella. About ten years ago, I was walking along a quiet London street one evening when it suddenly rained. I had no raincoat or umbrella.   2  And the people in the streets were fewer and fewer. As I was on my way to a party, I was afraid to get wet. So I stood in a doorway and waited for the rain to stop.   3  What was worse, there even wasn’t a person around, and still it rained and rained. At last a young man came to the place where I was standing.   4  As I hoped he would allow me to walk to the next corner with him, where I could get a taxi, I stepped out of the dark doorway where I had been standing.  5   As I suddenly appeared before him, the young man was so shocked that he dropped the umbrella. He ran away and disappeared into the darkness. I picked up the umbrella and continued my walk. I knew it would be hard in this big city to find the owner, so I’ve kept it ever since."

B. He held a large umbrella over his head.
