Case situation

Review the situation before choosing a next action.

A household member notices that the winter water bill is higher than the same period last year. There have been a few visitors and more laundry, but no one remembers a single major change. The player needs to separate ordinary seasonal use from a repeatable household pattern.

Your task: Decide which observations clarify the change and what the fictional case should check next.
