单选题 It was a beautiful spring morning. There wasn't a cloud in the sky, and the sun was warm but not too hot. So Mr. Black was surprised when he saw an old man at the bus stop with a big black umbrella in his hand.
Mr. Black said to the old man, "Do you think it's going to rain today?"
"No," said the old man, "I don't think so.
"Then are you carrying the umbrella to keep the sun off?"
"No, the sun is not very hot in spring."
Mr. Black looked at the big umbrella again, and the old man said, "I am an old man, and my legs are not very strong, so I really need a walking stick. But when I carry a walking stick, people will say, 'Look at the old man' , and I don't like that. When I carry an umbrella in fine weather, people say, 'Look at the foolish man'!/
