M: Hi, Mary!
W: Hello, Phil. How are you?
M: I'm fine. Where are you headed?
W: Oh, I'm on my way home from work.
M: I didn't know you had a job.
W: Yeah. I work part-time at a supermarket.
M: What do you do there?
W: I work in the produce section. Wrapping fresh fruit and vegetables. I also stock shelves. Sometimes when it really gets busy, I work at the check-out counter. Have you got a job, Phil?
M: Yeah. I do yard work for people. You know, cutting grass, pulling weeds, things like that.
W: I'd like doing that. It must be nice to work outdoors.
M: Sometimes it is, except when it rains or snows or gets too hot or too cold or...
W: Ha-ha. I guess every job has its shortcomings. There are times when I get really tired of carrying things around at my job. But a job's a job. Got to earn money for school.
M: Me, too. Tuition fee is high, isn't it? Well, I'd better get going. I've got to plant some trees for my neighbors this afternoon.
W: Well. Don't work too hard. Holding down a job, going to class, studying. Sometimes it can become too much for one person. Take it easy.
M: You, too. It was great seeing you, Mary.
