A note left on the door is a small bridge between people whose hours missed each other.

Households run on overlapping timetables that do not always overlap. One person leaves before the other wakes, one gets in after the other has gone to bed, and the note is what carries the day across the gap. It is not much, a line about the bins or the dinner or the fact that you were thinking of them, and it keeps two lives joined that would otherwise merely coexist.

If you regularly miss someone, leave something rather than assuming it will keep until the weekend. A sentence on paper by the kettle. Continuity is made of these small transfers more than of long conversations.
