Fog closed the funicular on my second morning in Bergen and I spent four hours in a cafe that had one working socket, waiting for a path to reopen. The notebook I carry for exactly those hours has thirty-one pages in it now, and almost none of the lines inside were written at a desk. Weather that cancels a plan is also the only weather that gives me time to write one.
What earns a page

The rule is that the line has to come from something I could point at. The signpost that was a rumour until I stood under it, the wet rope on a ferry deck, the tram stop at 06:20 with the weather to myself: specific things get written down, and moods do not. If I cannot see the object again in the frame, the line does not go in.
Second rule: one line per page, no rewriting. The first version usually has a word too many, and the corrected version I write in the margin three days later is the one I end up using. Keeping both on the same page means I can see what I was reaching for and where I overreached.
Third rule: the date and the place, pencilled at the bottom. Half of the notebook turns out to be useless a year later, and the dated pages are the ones that still carry the weather with them. An undated line about grey light could have come from any coast I have ever stood on.
The notebook itself is a cheap squared one that fits a jacket pocket, bought because a phone dies exactly when the weather turns. Paper does not need charging at a closed cable car, and a wet page still reads after it dries.
Why the bad days produce the good ones
Clear mornings are for walking, and I am out of the hostel by seven with the camera, which leaves no hours for writing. Grey afternoons reverse that: the path is a rumour, the cable car is shut, and the only thing open is a table near the window. Three of the lines I reuse most often came from afternoons where the entire plan collapsed before lunch.
There is also a practical reason. A caption written in the moment carries the actual temperature, and I can no longer invent that on a sunny evening in a different country. Wet cuffs, cold rail, coffee going lukewarm in my fist: those details arrive only while they are true.
I have tried keeping the same list in a phone notes app and lost the thread every time. Typing invites editing, and editing too early kills the rough edges that make a line worth keeping. The pen is slow enough that I write the good version first rather than the tidy one.
The four hours in that cafe produced six lines, of which two survived the month. That ratio is normal: the notebook is a filter, and most of what goes in is written for me alone on the day it happens.
What never makes it into a post
Most entries stay in the notebook because they are only funny to me, or because they describe a feeling with nothing attached to it. Others belong to a trip that did not go anywhere worth writing about, and a few are simply too good for a caption, so they sit and wait for a piece of their own.
The lines that do get used usually appear once, under a photo of the exact thing that produced them. Reusing one in three posts would flatten it, and readers notice repetition faster than they notice a weak adjective. Once a line has appeared, it is retired from the book as well.
Some pages get written down for a second reason: they record what the plan cost. The funicular was shut for four hours, the cable car ticket was refunded, the bus left from a different square. Those facts belong beside the pretty line because the next person going up that hill needs them more than I needed a mood.
How a page gets used later
When a set of photos needs captions, I read the notebook first and match pages to frames by date rather than by theme. It is faster than writing from scratch and it keeps the vocabulary of one trip consistent, so a week in the mountains does not borrow the words of a week by the sea.
Entries that never fit a photo become opening lines instead. A caption is too short to carry a full sentence with a clause in it, but the first paragraph of a post can, and that is where half of the notebook ends up.
When the fog finally lifted that morning in Bergen, I wrote nothing for the rest of the day. The page for that date holds a time, a place, and a single sentence about a funicular that never ran, which is still the most honest page in the book.
