I leave the lamp on when I read past the hour when the flat would otherwise be dark from the corridor side. It is a small brass lamp with a shade that throws a warm oval on the desk — not bright enough to disturb neighbours, not dim enough to strain the eyes. October evenings lengthen; the estate outside my window fills with the sound of televisions muffled by walls and the occasional lift ding from the block opposite.

Tonight I am reading essays, not writing them, though the distinction blurs when you keep a blog. The lamp was my grandmother's before it was mine, passed along without ceremony in a box of other useful things — scissors, spare keys, a notebook she never filled. I like that it continues to serve without demanding story.

When I stand to make tea I do not switch the lamp off. The habit started during a stretch of nights when I returned late from the library and did not want to enter a dark room. Now it is a signal: someone is home, someone is awake, someone is in the middle of a sentence. The city hum outside — traffic on Clementi Avenue, a distant MRT rumble, rain beginning soft against the glass — becomes the background track to reading.

I think about other lamps visible from my window: the corridor lights on timers, the blue flicker of a television, a phone screen on a balcony. Each a small declaration of presence. HDB life is vertical intimacy without necessarily knowing names. We share light patterns and laundry schedules and the timing of rubbish chutes.

At eleven I close the book and leave the lamp on anyway while I wash cups in the kitchen. The water runs hot quickly; Singapore flats do not make you wait for comfort. I look out the kitchen window at the carpark below, cars settled for the night, a cat crossing between pillars with purpose unknown to me.

Back at the desk I write three lines about the lamp, then a fourth that ties the light to the window and the window to the corridor beyond my door. Writing at night feels different from morning kopi writing — less social, more confessional without being private. The blog receives whatever I type; the lamp witnesses without judgement.

I will switch it off when I move to the bedroom, but not yet. For now the oval on the desk is enough company. Outside, the estate completes its slow transition toward midnight. Inside, a reader finishes a chapter and begins the small ritual of saving a document titled with a phrase he hopes will still make sense in the morning. The lamp I leave on is not a symbol. It is simply what I do.

October nights in Clementi sometimes bring sudden rain against the window — not the dramatic storms of the monsoon months, but a polite tapping that makes the lamp feel warmer by contrast. I listen and turn a page. The corridor outside my flat is quiet except for a door closing two units down.

When I finally stand, I touch the brass base the way you touch a familiar railing on stairs you climb every day — confirmation that you are where you think you are. The lamp goes dark. The estate continues lit by other people's choices. Mine will return tomorrow.
