You'd enter the library, and sit down behind a librarian, but unaware to her, she didn't see you sit down behind her, thinking no one is watching her, she'd slowly take her flats off, exposing her bare. Sweaty. Smelly soles to you, as she plays with her feet underneath the desk, you'd stare at her feet. As she stays unaware of your presence...

"I wonder how the other librarians are doing..."

She'd mumble, giggling as she played with her feet once again.
