M: Hey, Alice. What are you doing here?
W: I am looking for an apartment to rent. And you? Looking for an apartment as well?
M: Yes. Since my parents’ house is too far away, I need to find an apartment closer to my school. So, what are you looking for?
W: All I need is a place with a bed and a desk. Of course, the place should have a kitchen so that I can cook my meals. I will be living on a very tight budget and will have to watch every time.
M: Me too. I cannot work full-time this term. I will cut down on my workload to spend most of the time on my studies. So, a safe and decent (可接受的，像样的) apartment is all I need.
W: How long have you been looking for?
M: I just started this week.
W: It is not easy to find an apartment to your liking (你喜欢的) that does not cost a lot. I have been looking at the ads in the newspaper for two week, but I still have not found anything yet.
M: Really? Is it that difficult to find an apartment?
W: No, it is just that everything I like so far is too expensive and way beyond my reach.
M: Is it because they are very close to the school?
W: Maybe that is the problem.
M: Have you thought about sharing an apartment? If you want, we can find a two-bedroom apartment and share it. It may be cheaper that way.
W: That could solve our problem.
M: Wait! Maybe we should talk this over before we decide.
W: Right. For this plan to succeed, we need to come up with some sort of agreement or a set of rules.
M: Here is my first question: What do you do during the weekdays?
W: I have to work at Starbucks from 8:00 a. m. to 12:00 p. m., and then I have classes from 1:00 p.m. to 5:00 p.m. After that, I plan to go home. How about you?
M: Well, I have classes from 8:00 a.m. to 10:00 a.m., and then I go to the library to work until 2:00 p.m. After that, I plan to stay on campus until 6:00 p.m., and then go home.
W: It is my turn to ask the second question. Do you plan to have your friends over at the apartment very often?
M: No, not on weekdays. I want to finish my homework during the weekdays as much as possible. I think half of my weekends will also be reserved (保留，留出) for homework. If my friends do stop by, it will probably be during the weekends.
W: Good! I plan to do the same thing during school time.
M: It seems that it may work to share an apartment with you.
