Question: M: Really? W: Yeah, five of us. Why don't you join us? We're getting to Keswick on Friday. Then we're going boating on Saturday. And on Sunday, we're going to do some shopping. Then I will take some time to visit my aunt Lucy. M: You're not going to camp, are you? Isn't it a bit cold? W: No, we're not. It is a bit cold. We're staying in a country inn. It's not like five-star hotels or anything. But it's really comfortable. M: Hmm, sounds interesting. You know, it's the boating that I don't like. W: Well, what are you up to? M: Sit on my sofa all weekend and watch the DVDs I've just bought. And that will be a busy weekend. I may finish watching Friends. W: I don't know how you can do that all weekend, Gordon. I'd get bored. M: I know, I know. But that's really what I want to do. What was said before this conversation?
