Mr Fields: Camford 24689.

Louise: Hello, could I speak to Mr Fields, please?

Mr F: Speaking.

LP: Hello, Mr Fields, my name’s Louise Platt and

I live next door to your aunt, Mrs Grey,

in Newton street.

Mr F: Oh, is there something wrong?

LP: No, no. Well, there isn’t an emergency or anything

like that. But I would like to talk to you for a moment

about Mrs Grey. I’m very worried about her, you see.

Mr F: Is she ill?

LP: No, it’s not that. It’s just that I went round to visit

her because, you know, she lives alone and I’ve just

moved to the area and well, I want to be

neighbourly, you know.

Mr F: I’m sorry, but what’s the problem?

LP: Well, that’s it you see, I said she should give me a

number to ring, if ever she was ill or if there was an

emergency. You know, someone in the family to get

in touch with, because she’s an old lady, you know...

MrF: Look, Mrs... er...

LP: Platt, Louise Platt.

Mr F: Look, Mrs Platt. I don’t mean to be unkind and I’m

sure you mean well, but.. .if my auntie’s well, I really

don’t see why you are phoning me. I’m a very busy

man but I do go and see my aunt quite regularly and

you seem to be suggesting that she’s neglected in

some way, and really I can assure you that’s not the case.

She’s a very independent old lady and

she won’t thank you for interfering.

LP: Yes, but the problem is Mr Fields, that that old

house is so dangerous, I’m sure there’ll be

an accident if nothing’s done.

Mr F: Dangerous? In what way dangerous?

LP Well, the electricity for a start.

Mr F: What’s wrong with the electricity?

LP: Well, apart from the fact that it’s all so old and

needs rewiring there are certain things that are really

very dangerous.

Mr F: What, for example?

LP: Well, she’s got a socket right above the kitchen sink

and you know that’s so dangerous. The flex from the toaster

trails across the washing up water. It’s dangerous to touch plugs

or sockets with wet hands or splash them. That socket should be

taken out at once.

Mr F: She’s lived there for thirty-five years and nothing’s ever happened.

LP: That doesn’t mean nothing will happen. She’s also

got a socket in the bathroom, which is not a good idea at all.

And all the sockets are so old that they don’t have switches and you

know switch sockets are so much safer. And, of course, there aren’t

enough sockets in the living room and then she’s got so many

appliances working off one socket that I’m sure she’ll overload the system.

She’s using old adaptors with three plugs in - all the flexes get mixed up

and tangled together and that’s such a dangerous thing to do, you know.

And then upstairs the live flex is just pinned to the wall...

Mr F: OK, OK Mrs Platt. Listen, I’ll go round and check these

things if you like and if my aunt wants something

done about them, maybe I can help her iz some way.

Well, really the whole house needs rewiring, it’s the

only answer. And by the way, do tell her not to put wet

clothes over the electric heater, won’t you?

As I say, I’ll speak to my aunt...

LP: Anyway, my husband’s an electrician, so if you want to

get the work done cheaply, because these things cost

such a lot of money, don’t they?

Mr F: Thank you very much, but I think I’ll let my aunt decide about that.

Thank you for calling. Good bye Mrs Platt.

LP: Well.. .Why don’t you just have a word with him. hello... hello...
