The courtesy trot
A car stops to let you cross, and between one kerb and the other your body produces a gait it uses nowhere else. Not your walk. Not your run — a run would announce an emergency and embarrass everyone. Something in between: elbows in, a small springing at the knee, six or eight elevated steps that die out the instant you reach the far side. Every adult performs it. Nobody was taught it. The courtesy trot.
Do the arithmetic the trot is careful never to do. A traffic lane is about three metres wide, and the trot lifts you from roughly five kilometres an hour to roughly seven. Across the strip of road the driver actually occupies, the saving is a second — two, generously, for a wide crossing taken at full bounce. Nobody has ever trotted for the second. If seconds were the cargo, the whole performance would be a rounding error, politely delivered.
What the driver spent on you is stopped time, and there is the problem the trot exists to solve: you cannot hand time back through a windscreen. A wait has no refund mechanism. What you can do is spend something of your own where the creditor can watch — and effort is the one currency you carry that stays legible at thirty metres through glass. So the trot is exaggerated on purpose. The bounce is bigger than the speed it buys because the bounce, not the speed, is the payload: effort, typeset for distance.
It looks, at first filing, like the fifth page of the toll — this site keeps a thread on waits that cannot be shortened and charge anyway. But check that statute's teeth. The toll's pages pay into schedules nothing will move — a boil, a door timer, silences counted in a page's own source — and the payment never buys a second back. The driver's wait fails on both counts: it is the one wait in these pages its payer can actually shorten, and the trot is the shortening, by exactly the second nobody is counting. A toll vanishes into the interval. The trot arrives; it is addressed. Its statute book is the unwritten one — the same law the apology wave answers to, with nothing new to teach that thread — but its business is not the law. It is the currency the law gets paid in.
The proof is the alternative. Cross at a flat walk feeling the sincerest gratitude of your life, and the driver receives nothing. Between strangers who will part in four seconds there is no channel for an interior; whatever you feel in there is a rumour that never leaves the building. The footpath settles passage with broadcast intention, the gaze aimed like a turn indicator; the motorist's flat palm is thanks in the only currency that fits through glass; the trot is the same word in a third alphabet, spelled with the whole body. None of these signals report the feeling. Out here they are the feeling, in the only form that has standing: un-trotted gratitude, like an un-waved thank-you, is not thanks kept private. It is a debt denied.
You trot, notice, even for the driver a red light stopped — someone who surrendered nothing, whose wait no gait of yours could spare. The form has come loose from the ledger, which tells you what it was really for. The second was never the cargo. The cargo is the visible spending: thanks printed large enough to read from a driver's seat, in a script that exists only while somebody is watching.
