Conversation 1
M: Hi, Sally. Welcome back. How was the West Coast
W: Terrific. I had a wonderful time. It was really nice to get away from the city for a while.
M: What do you think of L. A.
W: It was all right. I liked it better than I thought I would. It’s very clean and spacious, and it’s got lots of trees. The problem is transportation. The bus service is terrible, and of course, they don’t have a subway, so it’s a little difficult to get around. We had to rent a car.
M: And what did you see
W: Oh, the usual things. We took a drive around Hollywood and looked at the stars’ homes, and then we went to Universal Studio and Disneyland.
M: How did you like Disneyland
W: It was great. We really enjoyed it. We took all the rides, some of them twice, and had a lot of fun. I felt just like a kid again.
M: Was the weather good
W: Oh, yeah. It was nice and warm in L. A..
