M: Sara, I’ve been looking forward to our yearly campout for three weeks. It’s going to be a wonderful day for hiking tomorrow. The great outdoors. Camping under the stars. This is the life.
W: Yeah, but Paul, I’m a little worried about the weather. The weatherman said it was going to rain later tonight.
M: Ah, nonsense. Nothing can spoil our adventure. Those weather reports are never fight.
W: And it said there was a chance of high winds.
M: Ah. Don’t worry.
[thunder]
W: Paul. Paul. Did you remember to bring our raincoats just in case, like I told you?
[light rain]
M: Uh... no. I left them on the front porch.
[heavy rain]
W: What are we going to do now?
M: We’ll have to sleep in the car! Hurry, get in!
[door shut]
W: So, Paul, what are we going to do now?
M: How about playing a card game?
W: Uhh. I left them next to the picnic table.[Hmmm]
Hey, you don’t want me to go out in this rain and get them, do you?
M: No. That’s okay. So what now?
W: Well, we could head down the mountain and stay at that hotel we passed on the way up.
M: Hmm, that’s a good idea.
