F: Did you know it was going to rain today? ,M: Absolutely not. This comes as a total shock to me, especially since the paper said mostly sunny. ,F: Well, I guess the paper must have meant mostly sunny somewhere else.

This one is all wet now. ,M: No. But I have got some folding chairs in the car. Will they do? ,F: They'll be just fine. I'm really hungry.
