听力原文：M: Hi, honey. I'm stuck in traffic. There has apparently been a big accident up ahead. We are just not moving. W: That's too bad. Where are you? M: I'm on the Garden City expressway near the sport stadium. I was on my way to drop off some samples at a new client's office and then I was going to pick up Billy from kindergarten. But now I'm afraid I won't be able to get there on time. Is there any chance you could get away early? W: Should be fine. What are the speakers mainly discussing?
