Given the question "Why does John want to buy a bicycle?" and the answer "Because he wants to begin bicycling to work and get some exercise.", write a conversation that might have happened.
A:
W: Hi, John.M: Oh! Hi, Laura. What are you doing here?W: Uh, I'm usually here on weekends. It's my uncle's shop. So you are looking for a bike?M: Yeah. Now that the weather is warming up, I thought I should get some exercise instead of taking the bus all the time.W: Well, that's a good idea and you come to the right place. Do you know what you like?M: Well, I don't want a racer or a touring bike or anything like that. Mostly I'll just be using it to get me back and forth from work.W: How far is that?M: About four miles.W: Are there a lot of hills on the way?M: Some, I guess. But maybe I should tell you at first that I only got 150 dollars. Can I get anything decent for that?W: Well, you are not going to get anything on the top of the line. But we do have a few trade-ins in the back that are in good condition.M: That sounds good.W: And you are right. For the kind of ride you are going to be doing, the most important thing is comfort. You want to make sure it's the right height for you? Follow me and I'll show you what we've got.
