Mom:  Come on, Jack!
Jack: Oh, no! Where's my bag?
Mom:  Hmm…is it on your desk?
Jack: No. And it's not under the chair.
Mom:  Oh! It's on the sofa.
Jack: Thank you, Mom. Err…where's the map?
Mom:  I think it's in your grandparents' room.
Jack: Yes, it's on their bed! And my hat?
Mom:  It's on your head!
Jack: Oh, yeah! Haha!
