The Underground
Sheila: We can walk to the hairdresser’s, can’t we?
Mrs. Hunt: Yes, but we might be late, Sheila. I think we ought to take a taxi. 
Sheila: We haven’t got to take a taxi.
Mrs. Hunt: Yes, we have. I’ve got to be there by ten fifteen.
Sheila: We can go by tube, can’t we? 
Mrs. Hunt: Yes, we can but there isn’t a tube station near the hairdresser’s.
Sheila: Yes, there is.
Mrs. Hunt: Good. We might get there more quickly by tube than by taxi. 
Sheila: And the tube isn’t as expensive as a taxi. 
Mrs. Hunt: How much is the fare?
Sheila: It’s the same as the bus fare, isn’t it – about ten pence?
Mrs. Hunt: No, I think it’s more than the bus fare. 
Sheila: You might be right.
Mrs. Hunt: Or I might be wrong.
