What’s the matter, with the man?

W: Hello, Larry, dear, where are you now?
M: I’m on my way home. And that’s why I’m telephoning.
W: What’s the matter? You haven’t had an accident, have you?
M: No, it’s much sillier than that. I’ve run out of petrol!
W: Oh, Larry! What a silly thing to do!
M: It isn’t my van, of course, and I didn’t know the petrol gauge was broken. It says haft-full, but there isn’t any petrol in the van at all. And I’m at the telephone box fourteen miles from Brenton. I’m miles from anywhere.
W: Can you buy some petrol?
M: There aren’t any buses. I can walk, I suppose. W: How far is it?
M: About six miles.
W: If you walk to Church town, and then back to the van, that will be twelve miles. You can’t walk six miles with a full can of petrol.
M: I haven’t got a can, anyway. And I haven’t got any money.
W: That’s a problem. Let me think! I’ve got an idea. Ask your dad to drive your car to you. He can buy some petrol, and you can put it in the van. You can drive the van home, and he can drive the car.
M: It’s a good idea. Thanks.
