input question: W: Hi! Well, I talked with my teachers before I left about the work I would miss. Besides, my aunt in Denver made me study a lot there. M: I thought she was your rich aunt. W: Not very. But she didn't have any children to raise, so she does have some money, even though she was a teacher. M: How was the holiday? W: Cold, at least three of the days I went. And I saw so many people on the mountain on Washington's Birthday. M: The beaches here were full on Washington's Birthday, too. It really was warm here, so lots of people went swimming. W: Well, we should have stayed home that day. There were so many people. We took the train over to the mountain, so at least we didn't have to drive. It is a good thing we did-there were so many cars and buses, and no place to park anywhere. M: Just like the beaches here. What was said before this conversation????
