How do we describe the neighbors’ son?

Jason: How are your new neighbors, Kelly?
Kelly: They seem nice enough, but they have a son who is driving me crazy.
Jason: What do you mean?
Kelly: (8[A])He comes home every night around 10 with his car window rolled down and radio blaring. It stops as soon as he turns his car off. but by then, the kids are wide awake.
Jason: Oh, no.
Kelly: Oh, yes. Sometimes it takes me midnight just to get them to settle down again.
Jason: Have you tried talking to them?
Kelly: We haven’t even really met them yet, except to say a quick hello, I have to get off on the wrong foot.
Jason: You are not going to like them when you do meet them if you keep on simmering.
Kelly: (9[B])I know, but I feel stupid complaining, It’s not as though he’s blasting stereo all night.
Jason: You said yourself it’s driving you crazy.
Kelly: Well, you know how early I have to be here at the office. I just have not got enough sleep aid neither have the kids. They are so irritable when I get home in the afternoon.
Jason: (10[C])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 other children, and they will be sure to ask about yours.
Kelly: Yes, and then what?
Jason: (10[C])And then you could mention that the hardest thing at this stage is getting your kids to go to sleep at night.
Kelly: And keeping them asleep.
Jason: That’s the idea and you should do it soon. The longer you wait, the harder it will be to do politely.
