I'm not an electrician, but perhaps I can see what's the matter. Nora: I plugged it in this morning, and for a little while it worked beautifully, but then it suddenly went off — So it must be the iron itself that's wrong. Harry: No, wait a minute. It may be the plug, or the flex. Oh, Nora! Look at this! One of the wires has come right away from the plug. No wonder the iron didn't work. Nora: Do you think you could mend it? Harry: Easily. Nora: Don't you need a screwdriver? Harry: No, I can do the whole job with my penknife. You know, Nora, if I can light the fire, or cook breakfast I don't see why you can't mend a piece of wire. Nora: I know, darling, I'm so ashamed, but I'm afraid of electricity. Harry: But my dear Nora — if you pull the plug out of the socket there can't be any electricity in the wire!
