听力原文：W: You got a call from your mechanic at the garage. He said your car is ready for pick up, and he wants you to give him a call as soon as possible. M: That's the best news I've heard all day. I am having such a hard day, and I am glad to hear that one of my problems is now solved. In fact, I was just thinking about how I was going to pick up my parents tonight. They're coming in from Florida to see me. W: Hasn't it been a while since you last saw them? I remember you telling me earlier this year that you really should go and see your parents, but you couldn't because of work. M: Yes, it has been really hectic this year, and I just couldn't take a holiday yet. That's why my parents decided to make a trip out here. Who called the man?
