M：I really don’t know what to do this summer. I can’t afford to just sit around, and there don’t seem to be any jobs available.

　　W：Why don’t you try house-sitting? Last summer my friend Margaret house-sat for the Dodds when they are away 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：It wasn’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 a little like baby-sitting, expect you are taking care of the house instead of children.

　　W：The Student Employment Office still has a few jobs posted.

　　M：Do you have to fill out an application?

　　W：Margaret and Eric had to interview with the house owners and provide three references each.

　　M：That seems like a lot of trouble for a summer job.

　　W：Well, the house owners 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 things probably aren’t paid then?

　　W：Usually they’re paid anyway just because the house owners don’t want to make a fuss. But if the house owner reported it, then the house-sitter wouldn’t be able to get another job. So why don’t you apply?

　　M：Yeah, I think I will.
