documents: #Person1#: Where were you when the sandstorm struck yesterday afternoon?
  #Person2#: I was at home. I was off work yesterday. What about you?
  #Person1#: I was caught in it. I was riding a bike in the street when I noticed Brown clouds coming from the northwest. Soon it was blowing hard and it became very dark.
  #Person2#: So what did you do?
  #Person1#: It was impossible to ride anymore. So I walked but there was so much dust in the air that it was very difficult to breathe. And it was so difficult to walk in the wind. It took me nearly half an hour to get to the post office, but usually it takes no more than 15 minutes.
  #Person2#: How did you feel in the sandstorm?
  #Person1#: Very frightened. I had never been caught in such a bad one. All the vehicles move very slowly in it, but still there were accidents.
  #Person2#: That's true. It is said that 3 car accidents happened during the sandstorm and all of the cars were slightly damaged. But Luckily there were no deaths or injuries because they were moving very slowly.
  #Person1#: But the government must do something to stop sandstorms.
