TOM: What are we going to do? I can't get the car out of this ditch. I'm stuck!
SUE: I'm worried, Tom. I haven't seen any other cars for almost an hour.
TOM: I know. This is terrible. What can we do? This snow doesn't stop falling!
SUE: I told you we should have stayed in town today.The weather report said 100 percent chance of snow.Why did you want to come up here?
TOM: I wanted to show you the cabin. We only had another half-hour to go.
SUE: Well, now we're stuck. What can we do?
TOM: I don't know.
SUE: I've heard that when this happens, it's important to save energy.
TOM: What do you mean?
SUE: We're stranded here, Tom. We may be here a long time.We need to conserve the gas in the car. The car's energy is what will keep us warm.
TOM: I have plenty of gas.
SUE: Yes, but the gas and the battery both have to stay working.We can't just let the car run and run.If we do, it will die soon. Then we'll freeze.
TOM: So what can we do?
SUE: Turn the lights off.Then, run the car and the heater only about fifteen minutes every hour.That will conserve the heat as long as possible.
TOM: Alright. That's a good idea.
SUE: I wish we hadn't come up here. Now we'll probably be here for days.
SUE: Yes, it happens.That is what happens in big snowstorms. People get stranded for days.
TOM: Oh, my God! It's good we have food.
SUE: Probably we'll survive.But turn the car off for about forty-five minutes. Then we'll turn it on again.
TOM: Okay, I'll follow your advice.
