Why did the man want to go to Africa?

W: You’re leaving Brighton! But why? What are you going to do?
M: I’m going to Africa. I’ve got a job as a doctor with a medical team.
W: What ! You’ re joking !
M: No, I am not kidding, Rosie. I’m going to miss you very much and I don’t want to end our friendship.

W. Alan, have you got a meeting in Edinburgh?
M. Yes. I’m going to see some important persons on the 20th. Why?
W: Because I’m going to visit Glasgow on Wednesday and it’s quite near Edinburgh.
M: Ah... I’m going to drive there tomorrow, are you coming with me?
