What are the speakers trying to do?

W: Did you know it was going to rain today?
M: Absolutely not. This comes as a big shock to me, especially since the paper says mostly sunny.
W: Well, I guess the paper must have meant mostly sunny somewhere else. But since we’ve come out this way, why don’t we just move the blanket under that tree?
M: That’s a good idea. It looks like it’s still dry there. So as long as it doesn’t start to come down any harder.
W: You didn’t happen to bring us a space blanket, did you? Because this one is all wet now.
M: No. But I do have some folding stools in the car. Will they do?
W: They’ll be just fine. I’m really hungry. So while you’re there, how about bringing the food?
M: I thought you were bringing the food.
W: This is unbelievable. Just I went so hungry, this would be really funny. So what now?
M: What’s the name of the restaurant which you like so much?
