  #Person2#: Well, I saw this old man. He was kind of holding his bag like this. He just left the bank and I was still queuing up to collect my money, but I was near the door. Now this young man came running past him and tried to get the bag.
  #Person1#: And they both fell down?
  #Person2#: Yeah, and the young man ran away, and the poor old man fell on the sidewalk, still holding his bag tightly. And we managed to help him up. Now can I go back in to collect my money?
