W: Excuse me. Do you live here?
M: Yes, I’ve lived here in Edinburgh all my life. My name’s Rory McDonald. How do you do?
W: Hi, I’m Chris Hudson from Phoenix, Arizona. I’m an oil engineer. I’m on my way to London on business.
M: How long are you staying in Edinburgh?
W: Just a day. What can I see here in twenty-four hours?
M: Well, most tourists want to visit the Castle. It’s on Castle Rock. It’s where the Scottish government used to be. From there you can walk down tile Royal Mile.
W: What’s the Royal Mile?
M: It’s a narrow street of medieval houses. It’s worth seeing. Then you really should visit Holyrood Palace.
W: Who lives in the Palace?
M: No one, except the Queen when she comes to Edinburgh, which is usually once a year. But the kings and queens d Scotland used to live there before Scotland was united with England,
W: When was that?
M: That was...er, let me see...in 1603.
W: You seem to know a lot about Scottish history.
M: Aye, well, I’m a McDonald of the McDonald clan. You know there are clans in Scotland, and we are all proud of our history.
W: Does that explain the kilt you’re wearing?
M: Aye. Each clan has a special kilt.
W: I’d like to buy a kilt for my husband.
M: You can buy them in Prince Skeet. It’s the best street for shopping.
W: What else should I buy?
M: Why don’t you buy some sweaters? Scottish sweaters are famous for their quality. And you must buy some whiskey. Of course you know that’s our national drink.
W: Yes, I’ve already bought the whiskey.
M: Good. But remember you mustn’t put ice in it. That spoils the flavor!
W: Oh，we Americans put ice in everything!
