Summarise a Year of Household Rota Chaos Into Next Year's Fairer Rota

The rota fell apart around March and everyone has been improvising ever since, with the same one or two tasks causing arguments all year. This spots the actual pattern of who ended up doing what, identifies the tasks that kept slipping, and builds a simpler rota for next year with a rule for handling holidays and illness.

<task>
**Summarise** the past year and build next year's rota:
1. Identify the recurring pattern of who actually ended up doing which tasks, regardless of what was originally agreed
2. Identify the specific tasks that kept getting missed or argued over
3. Propose a simplified rota for next year that directly addresses the worst friction point
4. Suggest one rule for handling exceptions, such as holidays or illness, so the rota does not collapse the first time something changes
