Who is that man?



Harry is looking at a man in the street. He is talking to Jack about the man.

Harry: Who's that man with the black bag?

Jack: I can't see a man with a black bag.

Harry: He was standing at the door of that house a moment ago. Now he's walking down the street.

Jack: Oh, that man. I don't know who he is. He's a stranger.

Harry: Look at the man who's running after him.

Jack: Yes. Perhaps the stranger is a thief.

Harry: I don't think so.

Jack: Wait a minute. I can recognize the man who's running after him. It's Mr. Green.

Harry: Now I remember. Mr. Green told me yesterday that his brother was coming.
