What does the man want to do this summer?

M: I really don’t know what to do this summer.(1)I can’t afford not to work.
W: Why don’t you try house-sitting?(2)Last summer my friend Margaret house-sat for the Dodds when they went away on vacation.(3 - 1)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: It wasn’t that easy.(3 - 2)She had to mow the lawn and water the house-plants. And when Eric house-sat for Dr. Cohen, (3 - 3)he had to take care of her pets.
M: House-sitting sounds like a good job. I guess it is a little like baby-sitting—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 as well as an application.
W: That seems like a lot of trouble 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 throw wild parties in their house, or move a group of friends in with you.
M: House-sitters who do that sort of thing probably aren’t paid. I think I’ll give it a try. Thanks for your information.
