We started the shared calendar to stop arguing about who does what, which in retrospect was optimistic. The rule was simple. Anything that takes more than ten minutes and benefits both of us goes in the calendar, with a name attached. Shopping. The tax return. Calling the plumber and then calling the plumber again. After six weeks we looked at it properly. The totals were closer than either of us expected, and for about an hour this was a pleasant discovery. Then my partner pointed out that the calendar had recorded only the events, not the noticing. She meant this: somebody had to know that the tax return was due, that the plumber had not called back, that we were nearly out of the coffee we both drink. That work does not appear in a calendar because it has no start time. It is the work of holding the whole system in your head, and it was almost entirely hers. I disputed this at first, and then I tried an experiment. For two weeks I would not be reminded of anything. Whatever I failed to remember would simply not happen. Several things did not happen. One of them mattered. The interesting part was not my failure, which was predictable, but the strange discomfort of the fortnight itself. Remembering everything is a low, constant hum. It does not feel like work while you are doing it, and it becomes visible mainly in its absence, which is a poor design for something you want recognised. We still keep the calendar. It is useful for the plumber. But there is a second list now, on paper, on the fridge, and the only thing on it is whose turn it is to be the one who notices. It changes on Sundays. Neither of us likes our weeks.
