Cute: Hello, my name is Cute, Agent Cute.
Mr Pill: My name is Mr Pill. How can I help you?
Cute: I'm looking for Robin MacWizard. He is lost. You live in 19 Crescent Road, don't you?
Mr Pill: Yes, I do. I'm his neighbour. The boy's name is Robin, but we always call him Rob. His parents do it too.
Cute: Is he a nice boy?
Mr Pill: I'm not sure. He is OK, but he never helps his mother and he doesn't say "Hello" to the neighbours.
Cute: I see. And his mother... What can you tell me about her?
Mr Pill: Oh, she's a very nice lady.
Cute: She works in a bank, doesn't she?
Mr Pill: No, she doesn't. Sir James, her husband, is a bank manager. Lady Elizabeth doesn't work. She is very
busy with her children and the house.
Cute: So Rob has brothers and sisters, doesn't he?
Mr Pill: Yes, he has a sister and a brother. I often meet them when they are out for a walk in the park.
Cute: They walk together, don't they?
Mr Pill:No, they don't. Rob normally walks alone.
Cute: You don't like Rob MacWizard, do you?
Mr Pill: Not really.
