Terry: Which one?
Pat: The big one.
Terry: Where in the backpack?
Pat: In the side pocket.
Terry: The side pocket? Which one, top or bottom?
Pat: The bottom one.
Terry; Let's see... Now, I can't find it. Are you sure it was this backpack?
Pat: Oh, sorry, it must have been the other one.
Terry; The other one? Ah, yes, here it is, but it's in the top pocket. You'd better put some on, too, and then we can start getting the vegetables ready.
