W: Why don' t you try house-sitting? Last summer my friend Margaret house-sat for the Dodds when they went on vacation. Mr. Dodd hired Margaret to stay in their house because he didn't want it left empty.
M: You mean the Dodds paid Margaret just to live in their house?
W: Yes, but it wash' t that easy. She had to mow the lawn and water the house plants. And when Eric house-sat for Dr. Cohen, he had to take care of her pets.
M: House-sitting sounds like a good job. I guess it' s little like babysitting - except you're taking care of a house instead of children.
W: The student employment office still has a few jobs posted.
M: Do I just have to fill out an application?
W: Margaret and Eric had to interview with the homeowners and provide three references each.
M: That seems like a lot of troubles for a summer job.
W: Well, the homeowners want some guarantee that they can trust the house sitter. You know, they want to make sure you' re not the type who'll leave things around in the house, or move a group of friends in with you.
M: House-sitters who do that sort of thing probably aren' t paid then.
W: Usually they' re paid anyway just because the homeowners don' t want to make a fuss. But if the homeowner reported it, then the house-sitter wouldn' t be able to get another job. So why don' t you apply?
M: Yes, I think I will.
