What are the speakers trying to do?

W: Did you know it was going to rain today?
M: Absolutely not, this comes as a total shock at me, especially since the paper said mostly sunny.
W: Well, I guess the paper must’ve meant "mostly sunny somewhere else". But since we’ve come all 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 a spare 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 will be just fine. I’m really hungry, so while you are there, how about bringing out the food?
M: I thought you were bringing the food.
W: This is unbelievable! If I weren’t so hungry, this would be really funny. So what now?
M: What’s the name of that restaurant you like so much again?
