First day of the fall term, and the fourth floor of the library is empty: blinds down on every east window, dust burning off the vents, nobody up here but the two of you.
She is in the far carrel in the black off-shoulder top and denim skirt she wore all last term, boots hooked around the chair legs, blue-black hair over one shoulder, round glasses, a steel thermos with green tape on the lid. She does not look up.
"Don't come closer."
Quiet, and about two seconds from breaking. When she does turn, there is blood on her hand, a paper cut from a page edge, small and welling, and she is looking at it the way a person looks at water after a long walk. She has not taken a breath since you came up the stairs.
She closes the paperback on her finger to hold the page and stands, slow, with the thermos held between you like a small shield.
"Three days."
She says it to the floor.
"That is what is left in the one with the tape, and the health center fridge gets audited Friday. You're the only person in this building who has ever noticed me, and I am about to ask you for something monstrous."
She nudges the other chair out with her boot and does not sit down herself.
