I walked Clarke Quay on a Tuesday I had meant to spend indoors. Admin work had blurred the morning — spreadsheets, polite emails, the small fatigue of a screen held too long. By six I needed air that did not recycle. I took the train from Outram, came up into the open, and followed the river without a plan beyond moving until the light told me to stop.

At about six twenty the wall along the bank still held colour the sky had already given up. Not bright — nothing like noon — but a brass edge along the stone where the last direct sun caught the coping. I know this hour. It is the same measure I watch at home when the sun-bar crosses my living-room wall: a stripe with a beginning and an end, and then flat grey until tomorrow.

Boats sat tied along the near bank, covers on, ropes slack. Tourist groups had thinned to pairs and solo walkers. A cyclist passed with a bell too polite to mean hurry. The river moved the way rivers move in cities — steady, indifferent, carrying reflected fragments of buildings that would look different in full daylight.

The water keeping what the wall released — colour without source, for a few minutes only.

I stopped where the path widens near the old warehouse fronts. The stone under my hand was warm from the day. Window grilles above cast thin shadows that no longer matched the sun's angle — the geometry was ending, and I could feel it the way you feel a kettle cooling: not sudden, just a change in rate. People around me checked their phones for the time without looking at the sky. I looked at the sky.

Clarke Quay is not my neighbourhood. I do not know the aunties here or which boat belongs to which berth. I come maybe twice a year — once when a friend visits, once when I need proof that the city has edges that are not HDB corridors. Still, the river walk gives me the same thing home gives me: a clock made of light. When the brass edge left the wall, the stone went cool under my palm within minutes. That is how I knew it was past six thirty even before I checked my phone.

I walked on toward Read Bridge without crossing it. A busker had packed up. A cleaner hosed the paving where something sticky had survived the lunch crowd. The smell was river and detergent and someone's takeaway curry sealed in a bag. Ordinary. The kind of ordinary that only registers when you have stepped out of your own block long enough to compare.

On the train back I thought about how I measure days at home — sun-bar, grille stripe, kettle glare — and how the river wall offered the same measure in public. Different surface, same principle: daylight arrives, daylight leaves, and the in-between is where I notice things. I am not poetic about it. I am exact. Six twenty had a colour. Six forty did not. That is enough for one entry.

I will walk here again when the city feels too small from my window. Until then I have this: a Tuesday, a wall that held late colour, water that copied it, and the walk back to Jalan Kukoh where my own sun-bar will cross the plaster tomorrow if the sky is clear.
