W: I'm not taking lessons anymore.
M: You're not？ I thought you wanted to get your driver's license this summer. Didn't you sign up for a 6-week course？
W: Yes, but after two weeks the driving instructor asked me not to come back.
M: I've never heard of a case like that. What about the remaining money？
W: Oh, The school gave my money back for the remaining 4 weeks.
M: Why was that？ Didn't you get on well with the driving instructor？
W: No, he seemed like such a nice man. At first we got along well.
