DEREK: You won't believe what just happened. KELLY: What? DEREK: I went down to change some money, right? KELLY: Yes. We need some. How much did you change? DEREK: I wanted to change around 5000 dollars. And you know the exchange rate. KELLY: Yes, it's about 35 pesos for every Taiwan dollar, right? DEREK: Not today. KELLY: What do you mean? DEREK: I went into the bank with my money, and I looked at the exchange board.At first I couldn't believe it. I thought I was reading the board wrong or something. KELLY: Why? DEREK: Because the board said 60 pesos for every Taiwan dollar. KELLY: Sixty? That's too much. How can that be? DEREK: I thought it was wrong too. It didn't make sense. KELLY: Just two days ago it was 35. How can it be 60? DEREK: So, I went up to the teller and started to exchange the money. And it's true.They really gave me sixty pesos for the dollar. KELLY: That's amazing! Really? How could it change so much in two days? DEREK: I tried to ask the bank teller why it changed,but she didn't speak English well enough.So I decided to go to the magazine shop. The one around the corner.And I bought an American newspaper. KELLY: What happened? DEREK: It seems that yesterday the Mexican government declaredit wouldn't pay back the loans it got from the World Bank.The government declared a default on the loans. KELLY: That's serious. DEREK: I know. The economy here is having serious problems.But because the government declared a default, the currency value went way down. KELLY: So now Mexican pesos are worth about half as much. DEREK: Yes, it's an amazing drop. KELLY: Wow. I feel sorry for the Mexicans. But it's good for us. DEREK: Yes, it's very good. We suddenly have twice as much money to spend here.Our hotel is now half as expensive as when we got here! Isn't that strange? KELLY: Yes, and you know what? DEREK: What? KELLY: I don't really like this hotel that much.So tonight, now that we are so rich,tonight why don't we stay in the most expensive hotel in town? DEREK: Why not? We should do it. Because now we can afford it.
