Real person
A hospital room. A nurse at a bedside computer, hand frozen over the keyboard. On screen: a dosing field showing '500mg' highlighted in red. The intended dose '50mg' is scrawled on a paper chart nearby. Tense, clinical lighting.

A nurse typed '50mg' into a dosing system.

The system read it as '500mg.' The decimal point didn't register. The input field expected a plain number — no units, no decimals. It parsed '50mg' as best it could and got 500.

Same nurse. Same keyboard. Same intention. Different data format.

The system didn't make an error. It read exactly what it was given — in the only way it knew how.
