TS: I see, can you hear anything from the computer?
M: No. nothing.
TS: Are there any lights on the computer?
M: Not that I can see.
TS: No fan noise?
M No.
TS: It may be the power cord has come out, where is the computer?
M: On the floor, under my desk.
TS: Ok, have a look and see if you can see the power cord.
M: OK, I'm just crawling under the desk, I'm trying to see round the computer. No, I can't see the power cord.
TS: You can't see it? Why not.
M: It's too dark
TS: Why is it dark?
M: All the lights are out.
TS: Why so?
M: There's a power cut.
TS: I understand, do you still have the boxes the computer came in?
M: I do.
TS: Well, I want you put everything into the boxes and send it back to the manufacturer.
M: What should I tell them?
TS: Tell them you are too bloody stupid to own a computer. Goodbye.
