What bothers Nacy about her neighbor’s son?

W: How are your new neighbors, Nancy?
M: They seem nice enough, but they have a son who’s driving me crazy.
W: What do you mean?
M: He comes home every night around 10 with his car windows rolled down and radio blaring. It stops as soon as he turns the car off. But by then Brian and Lisa are wide awake.
W: Oh, no.
M: Oh, Yes. Sometimes it takes us till mid-night just to get them settle down again.
W: Have you tried talking to them?
M: We haven’t even really met them yet except to say a quick hello. I hate to get off on our own foot.
W: You are not going to like them when you do meet them if you keep on simmering.
M: I know, but I feel stupid complaining.
W: You said yourself it is driving you crazy.
M: Well, You know how early have to get up to be here at the office. I’m just not getting enough sleep and neither are the kids. They’re so irritable that I get home in the afternoon.
W: Maybe you could go over sometime with a little gift: a plant for the yard or something. Then you could ask about their son whether they have any other children and they’ll be sure to ask about yours.
M: Yeah, and then what?
W: Then you could mention that the hardest thing at his stage is getting your kids to get sleep at night.
M: And keeping them in the sleep.
W: That’s the idea. And you should do it soon, The longer you wait, the harder it will be to do politely.
