Money arrives on somebody else's timetable. The 28th. Thirty days from invoice, which in practice means forty-five. The council's payment run, which happens on Thursdays and not otherwise.
Watching a date on a calendar is its own kind of waiting, and most money anxiety lives in the gap between arrivals rather than in the totals themselves.
Stand back a year, though, and the arrivals do add up to something continuous. The flow is real. It's simply only visible from that distance.
