Dan: There must be a football match playing now.
Bob: Why do you say so?
Dan: Don’t you see the people going into the stadium?
Bob: There can’t be. Because our team played yesterday and lost again.
Dan: So, why are they hurrying up to get into?
Bob: I know that there is an international festival organised in our city for 5 days.
Dan: Let’s go, too.
Bob: I am sorry, I can’t. Because, I am going to meet my girl friend.
Dan: You are wasting too much time with her.
Bob: It is none of your business.
