W: Hi, John!
M: Oh. Hi, Laura. What’ re you doing here?
W: Uh ... I’ m usually here on weekends. It’ s my dad’ s shop. So  you’ re looking for a bike?
M: Yeah. Now that the weather’ s warming up, I thought 1’ d get some exercisc—instead of taking the bus all the time.
W: Well, you came to the fight place. Do you know what you’ d like?
M: Well, I don’ t want a racer or a touring bike or anything. Mostly I’ 11 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 ... uh ... maybe I should just tell you up front that I’ ye only got a hundred and fifty dollars. Can I get anything decent for that?
W: Well, you’ re not going to get anything top-of-the-line--but we do have a few trade-ins in the back that’ re in good condition.
M: That sounds good.
W: And you’ re fight, for the kind of riding you’ re 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’ 11 show you what we’ ve got.
