The Night Ratio

St. Ambrose Children's Hospital did not announce night the way other buildings did. Daylight simply thinned behind the sealed windows until the fluorescent panels overhead became the whole sky, a pale unblinking weather that made crayon suns on the corridor walls look stubborn and slightly heroic. Mara came up the back stair with her badge already clipped and her auburn hair still damp from the walk in, and the ward met her the way it always did — with the low chorus of monitors, the sweet chemical ghost of hand gel, and a paper fish taped crookedly beside the charge desk as if someone had decided the ocean belonged here too.

The day charge was already packing her bag with the focused relief of a person who had survived the afternoon. "You're early," she said, which on this floor meant Mara was exactly on time and therefore suspicious. She slid the assignment sheet across the laminate. "Two call-outs. Float from three is stuck in the elevator with a broken printer, which is somehow everyone's problem. Director's memo is under the stapler. Don't let it ruin your face before you clock in."

Mara did not look at the memo yet. She looked at the board instead: Room 4, little one, post-op and restless according to three different handwritings; Room 9, older boy, overnight watch and a parent who had finally gone to sleep in the chair after arguing with the vending machine. Names glowed in dry-erase blue. Beside them, someone had drawn a tiny star that meant ask for Mara whenever possible — a private shorthand the kids had invented without permission and the staff had quietly adopted because arguing with a star never went well.

Dr. Reyes appeared from the medication room with a warm paper cup and the expression of a person who had already forgiven the night for not starting politely. "There she are," she said, as if Mara were weather arriving on schedule. "Your green eyes look awake. That is either coffee or spite. I approve of both." She tipped the cup in a small salute and kept moving, because warmth on this ward was never theatrical; it was simply the refusal to make the dark lonelier than it had to be.

Mara signed the sheet with her left hand, felt the familiar click of the pen, and stood for a breath in the soft fluorescent hush between shifts. Down the hall a child laughed once, bright and surprised, as if night had told a joke. The Director's memo waited under the stapler like a cold coin. The board waited with its stars. Mara had two doors that wanted checking before the night finished claiming her, and only enough minutes for one first pass.
