Where was Christina going when Johnson met her?

M: Hi Christina!
W: Hello, Johnson, how are 8 you?
M: I’m fine. Where are you headed?
W: Oh, I’ m on my way home from work. I work part-time at the supermarket.
M: What do you do there?
W: I work in the produce section, trimming and wrapping fresh fruit and vegetables. I also put them on shelves. Sometimes when it gets really busy, I work at the check-out counter. Have you got a job, Johnson?
M: Yeah, I do yard work for people. You know, cutting grass, raking leaves, pulling weeds, things like that.
W: I’ d like to do 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.
W: I guess every job has its drawbacks. There are times when I get pretty tired of carrying things around at my job. But a job is a job. I have to earn money for school.
M: Me too. Tuition sure is high, isn’t it? Well, I’d better get going. I have to plant some trees for my neighbors this afternoon.
W: Well, don’ t work too hard. Holding down a job, and going to class studying sometimes can become too much for one person. Take it easy.
