Extend the Story - Add a Room

"Okay, okay, I'm putting them back, sheesh, don't have a breakdown, lady," you mutter, not very loud, leaving the items in question on the desk. You look at the plastic coins and start to ask, "Can I get anything with--" but one look at the librarian's face shows that not to be the best idea.
You take another look around the library, wondering if it's worth to wander around. It's pretty big, and some of those shelves seem to go back for miles. Maybe the subway is the way to go. On the other hand, the librarian bugs you; she looks and sounds like a pekingese with an attitude.
Uh-oh the subway doors are closing. Better decide what to do.

Ask the librarian why she's so tiny.
