Rain makes a particular kind of writing time. It is not the ambitious kind. Nobody begins a novel on a Tuesday afternoon when the light has gone grey, the heating is clicking, and someone downstairs is playing the same song for the fourth time. What rain offers is a small window: twenty minutes before the washing needs hanging, or the pleasant nothing that follows a cancelled plan. These prompts are built for that window. Each one is short enough to hold in your head, specific enough to get you past the blank page, and open enough that you will not know where it goes until you get there.

Set the Timer Before You Choose

The most common way a short writing session fails is not a lack of ideas. It is spending fourteen of the twenty minutes choosing one. So decide in advance and decide badly. Read the list once, take the first prompt that produces a small flicker of interest, and start writing before you can talk yourself out of it.

A few ground rules help more than they sound like they would:

• Fifteen minutes, one page. Not a page of a notebook — a page of anything. Stop when the timer goes, even mid-sentence. The unfinished line is tomorrow's invitation.
• No deleting. If a sentence goes wrong, keep it and write the next one slightly better. Crossing out is a different activity and it usually ends the session.
• Write the boring details. What is on the table, what the person is wearing, what they can hear through the wall. Concrete things carry a scene further than dramatic ones.
• Do not look for a moral. A rainy afternoon is not the moment for a theme. Theme turns up later, usually by accident, usually in the third paragraph of something that started as an argument about a bus.

Twenty Starters for a Wet Afternoon

Each of these assumes one character, one place, and something slightly wrong. Pick one and give yourself two hundred words to find out what.

Rooms and Weather

• A kitchen with the window open in the rain. Someone is cooking a proper meal for a person who is not coming.
• Two people under one bus shelter. One of them has been waiting since yesterday and has stopped explaining why.
• A hotel room where the radiator knocks three times at the same hour. Tonight, it knocks four.
• A conservatory with a leak. The buckets catching the water are labelled with names, in handwriting that is not the owner's.
• The last dry table in a café. Two strangers reach it at the same moment, and one of them has a very good reason to sit down.

Objects and Hands

• A key that fits nothing in the flat. It fits next door, and next door has been empty for a year.
• A library book returned with a pressed leaf and a phone number inside. Write the librarian's decision.
• Wet boots by the door. Everyone who lives here is accounted for, and the boots are the right size for nobody.
• A jar of coins labelled "for the ferry." Describe the person who counts it, and what they are avoiding by counting it again.
• A receipt found in a coat pocket. There is a second handwriting on the back, and it is yours.

Overheard and Half-Heard

• Begin with the line: "You can't keep doing that in the hallway." Do not explain it for at least a hundred words.
• A phone call heard through a wall. You can only make out the pauses, and you have started filling them in.
• A child explaining something to a dog, very patiently, in the tone of an adult who has been ignored all week.
• Two colleagues in a lift. One sentence each. Then the doors open and one of them does not get out.
• A song lyric misheard. Someone has built a small, private belief on the wrong words, and today they find out.

Small Disasters and Odd Rules

• The power goes out during a haircut. The scissors are still open. Write the next thirty seconds in slow motion.
• A town where nobody says the name of the river aloud. A newcomer asks directions to it.
• A wedding with the wrong cake. It is a good cake, but it belongs to a different wedding, and one guest recognises it.
• Someone has watered a plastic plant for two years, out of politeness, in an office where nobody will admit it is plastic.
• A house rule: at midnight, every apology spoken in the building becomes briefly audible to everyone in it.

Three Ways to Stretch a Prompt

If the fifteen minutes go well and you still have a little room, don't start something new. Push on the thing you already have. It is almost always more productive than another beginning.

Write the second page

Skip forward an hour, a week, or ten years in the same scene. Same characters, same room, different weather. The gap you jump over will do most of the work for you, and you will find out what the first page was actually about.

Change who is speaking

Take the same event and hand it to the least important person in the room: the neighbour, the person holding the umbrella, the one who took the coats. A shift in narrator is often the entire story, disguised as an exercise.

Cut the first line

Read what you wrote and draw a line through the opening sentence. Nine times out of ten the second sentence is the real start, and the first was only you clearing your throat onto the page.

When a Prompt Lands Flat

Some of these will not work on a given afternoon, and that is information rather than failure. If you get three paragraphs of nothing, stop. Do not force an ending onto a scene that never came alive; you will only teach yourself that writing is a chore.

Instead, save the scrap. Under the page, write down the one thing you liked — a name, a detail about the boots, a line of dialogue that surprised you — and leave the rest. Scraps collect faster than you expect. Four or five of them, looked at together on a different day, often turn out to be the same story told from different angles, and by then you will have the energy to write it properly.

Two quick rescues are worth trying before you give up. First, add weather and a physical task: someone has to carry something heavy up a flight of stairs while saying whatever needs saying. Second, lower the stakes. If the scene insists on being dramatic, make it about a lost glove instead and see whether the drama survives the move. It usually does, and it usually gets quieter and better.

A Short Ritual to Close

Before you shut the notebook, write the date at the top of the page and one line underneath it: the sentence you would keep if a stranger asked to read only one. That is your whole filing system. It takes forty seconds, it gives the session a shape, and it means that when the next wet afternoon arrives you open the notebook to something rather than nothing.

Then put the kettle on, leave the page where it is, and let the rain finish. Fifteen minutes of writing counts, even when it produces nothing you will use. The point of a small prompt is not to write something good on demand. It is to keep the habit warm enough that when the good idea does arrive, you are already at the table with a pen in your hand.
