Listen to a conversation between two students.

(woman) How’s it going, Mike?
(man) OK, I’m just trying to figure out what to do about this new bus schedule.
(woman) New bus schedule?
(man) Yeah, I take a bus from campus to my job downtown. I work there Tuesday afternoons, but the bus schedule changed. The bus I was taking is leaving earlier now and I can’t get to it in time because I’ve got chemistry class then.
(woman) Huh, yeah, they did change the bus schedule sometimes. It’s inconvenient. So what are you gonna do?
(man) Well, I talked to my boss and she said I could change my work hours and work at night instead. I’d start late in the afternoon and work till around midnight. And there is a bus that’ll get me down on time.
(woman) That sounds good. So you could just take a later bus to your job.
(man) Yeah, the only thing is if I worked late at night. I’ll be really tired and I have class early the next morning.
(woman) Yeah, but do you have any other choice?
(man) Well, yeah, another option is just to ride my bike to work after chemistry. I’ll be able to get to work on time so I could keep my same hours. It’s not that far. It takes about 15 minutes.
(woman) Hmm, that might be nice plus you get some exercise but it’ll be a bit uncomfortable riding your bike on days when there’s bad weather.
(man) Yeah, I’ll have to think about it.
