Across from my kitchen window, a third-floor lamp clicks on at 7:14 p.m. I have timed it across two weeks, not because I am obsessive but because the regularity feels like a gift in a season when everything else negotiates its schedule — rain, lifts, buses pretending to be on time. The lamp belongs to someone I have never met. Its shade is amber, its glow generous without showing the room behind it. Privacy maintained; presence announced.

I call it the blue hour lamp though by the time it lights the sky is already negotiating with streetlights. Blue hour, in my personal almanac, begins when the first domestic lamp appears opposite and ends when my own desk lamp joins the chorus. It is the hour I write least fluently and most truthfully — sentences shorter, adjectives suspicious, metaphors rejected for overstaying.

Window lamps are neighbourhood punctuation. They say: someone is home, someone is reading, someone is waiting for a child, someone is not waiting for anyone and enjoys the silence. Each lit rectangle is a sentence in a long paragraph called the block. When too many windows stay dark I feel uneasy, as if the building were holding its breath. When too many glow at once I feel crowded, even alone in my flat.

I once tried to wave at the lamp owner during a blackout drill. No response — perhaps they were out, perhaps curtains intervened, perhaps waving at strangers is still eccentric in Singapore. I respect the failure. Not all rituals require reciprocity. The lamp continues its schedule with municipal dependability while I continue mine: boil kettle, open notebook, pretend the view is not more interesting than the page.

On nights when I cannot write, I watch the lamp and invent biographies I will not publish. Retired teacher. Night-shift nurse pre-gaming sleep with warm light. Teenager avoiding homework beneath a bulb kinder than the ceiling fluorescent. The inventions change; the lamp does not. It is a fixed star in a constellation of laundry poles and air-con compressors.

Tonight rain threatens without committing. The lamp comes on early — 7:09 — as if it sensed the gloom. I match it at 7:11, two minutes late as always. Symmetry is not the point; acknowledgement is. Journal Wave takes its name from this ordinary synchrony between strangers linked only by sightlines. If you walk Dawson at dusk, look up. The town is full of lamps keeping time for each other without knowing names. That is enough poetry for one note.

Occasionally a curtain shifts and the amber square narrows — someone adjusting privacy, someone ending the day. I look away first, a habit from upbringing rather than policy. The lamp stays steady regardless. Reliability in a block is measured in watts and timing, not in friendship. I find that comforting: not everything requires intimacy to matter.

When I finally switch my own lamp off at midnight, the opposite window is dark already. The schedule resumes tomorrow. I sleep better knowing the sequence continues without my witness — a small proof that the neighbourhood runs on rhythms older than any single tenant, including me.
