How long will Anna still have to stay in London? Why does Anna want to improve English?

M: Er, Anna, tell me, how long have you been here in London?
W: I arrived ten days ago.
M: I understand you are taking an English course at this school.
W: Yes, that’s right.
M: When did the course start?
W: It started…er, five days ago.
M: How long does it last?
W: It lasts a month, and there are three hours of classes every morning. In the afternoon there are trips to places of interest in London.
M: I see. Why did you decide to take this course?
W: For two reasons, really. You see, I work in the Sales Department of a computer company, and I often have to speak English to customers, so I wanted to improve my spoken English.
M: You speak very well.
W: Thank you.
M: And the second reason?
W: It was a good excuse to see London.
M: Is this the first time you’ve been here?
W: Yes.
M: And are you living with an English family here in London?
W: No, I’m living in a hotel, but I think it’s better to live with a family. There are five French people staying at the hotel, so we speak French together. I haven’t met many English people yet!
