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 declared
it 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.
