the great bell tolls. you count without meaning to. ten strokes is a full hour and goes back to its sleep. twelve is also a full hour and a different sleep. eleven is neither: a number with one too many or one too few, depending on where you stand inside it.
this means there is a thing of yours that is half-finished — a sentence, a stitch, a small repair you began three weeks ago. the building has noticed it before you have. eleven is the building counting on your behalf.
do not finish it today. take it out, look at the place where you stopped, and turn one piece a quarter-turn. then put it down again. eleven asks for acknowledgment, not completion.
— field note: a bell that rings eleven twice in a day is rare and means nothing further. count once; do not count again.
