How to Start a Fictional Pen-Pal Exchange by Writing as Two Characters
To start a fictional pen-pal exchange with a friend, agree on a simple premise, give each character a distinct voice, and take turns writing short letters that leave the other character something to answer. You can do it by email, in a shared document, or on paper. Begin with one exchange and decide together whether to continue; either person can pause or stop whenever they like.
1. Agree on the shape of the activity
Invite one adult friend who might enjoy a small creative writing experiment. Explain the premise plainly: each of you will write as a character, and the characters will exchange letters within an invented setting. Keep the invitation easy to decline: “Would you like to try a two-letter fictional correspondence with me? No pressure if it’s not your thing.”
Before you begin, settle a few practical choices. Pick a format, a rough letter length, and a number of turns to try. For example, you might exchange two letters each, with each letter around 150–300 words. Those are starting suggestions, not rules; a postcard-length note or a longer email can work if both people prefer it. Make clear that there is no required response time, and agree whether either of you may skip a turn or end the activity without explanation.
It can also help to decide how you will separate the fiction from ordinary conversation. A subject line such as “Letters from Bracken Bay” or a greeting that includes the character’s name makes the frame clear. You can chat out of character about the activity whenever needed, including to change the premise or take a break.
2. Choose a premise that gives both characters something to write about
A useful premise sets a place, a reason for correspondence, and one small question or complication. It should give each writer room to add details without requiring extensive world-building. Try one of these adult-friendly setups:
A premise is a starting point, not a contract to sustain a plot. If you choose the observatory, for instance, the first letter can simply ask whether the caretaker has room to store the chair. The other writer can decide whether it is interesting, odd, inconvenient, or all three. Small, concrete circumstances make it easier to begin than a sprawling setting with a long list of rules.
3. Make two characters easy to tell apart
You do not need a full biography for either character. Give each one a name, an everyday role, one current aim, and a few habits that affect how they write. One might use short, practical sentences and include exact dates; the other might tell a story before getting to the request. Choose differences that can show up naturally in a letter.
A quick character card can be as short as this:
Then give each character a private question to carry into the exchange: What does Mara suspect about the chair? Why is Elliot so keen to identify its sender? You do not have to tell your partner the answers. A little uncertainty can give the next letter somewhere to go.
Distinct voice does not require exaggerated spelling, accents, or a pile of catchphrases. Word choice, sentence length, what a character notices, and what they choose to leave unsaid can create a difference. University writing resources describe voice and dialogue as ways to express character; for this activity, that suggests a practical test: if you removed the character’s name, could you still make a reasonable guess who wrote the letter?

4. Write the first letter with a clear opening and an easy reply
A first letter needs only a few jobs: introduce the character, establish why they are writing, offer one specific detail, and give the other character a natural opening to respond. For the observatory premise, Mara might write:
> Dear Mr. Finch, > The chair arrived at the observatory yesterday with your workshop label beneath the seat and no note explaining why it was sent here. I have put it in the east room, where it is currently blocking the cupboard containing the lanterns for next week’s open evening. Is it yours, and would you like me to keep it there until you can collect it? > Yours, > Mara Vale
That gives Elliot clear options: confirm or deny the chair is his, explain what he knows, and decide what to do about collecting it. A final question can help, but it does not need to sound like a questionnaire. A useful prompt is specific to the fictional situation; “What do you think?” is broad, while “Can the east room spare the chair until Saturday?” gives the recipient something concrete to answer.
This sample is an illustration, not a template you must follow. The letter could be playful, formal, or extremely brief, provided the other writer can understand the situation and find a way to continue it.
5. Take turns and add one manageable change at a time
Agree on the order before the first letter: for example, one person opens and the other replies, then each writes one more letter. If you are writing in a shared document, label each entry with the character’s name and date within the fictional world. With paper letters, you can fold or decorate them if that is enjoyable, but presentation is optional.
In each reply, pick up at least one detail the previous character introduced. Then add one new piece of information, choice, or obstacle. Elliot could say the chair is not his, explain that he restored a similar chair last month, and ask Mara to check for a faded mark underneath the arm. That advances the exchange without making the next turn difficult to write.
A helpful rhythm is: acknowledge something, respond to the practical question, then offer one fresh detail. A university dialogue exercise connects character-revealing language with moving a scene forward; here, a letter can do both by letting a character’s choice advance the shared situation.

6. Keep the correspondence readable and flexible
Letters can contain more than dialogue: a short description of the room, a list tucked into the envelope, or a character’s comment on the weather can help make the setting tangible. Use details that matter to this particular letter. If the chair is blocking the lantern cupboard, a mention of the upcoming event is useful; a page of background about the town’s founding may not be needed yet.
When revising, read the letter once as your character and once as your friend’s character. Check that the speaker is identifiable, the immediate situation is understandable, and the ending offers a possible next move. University College Dublin’s writing handout recommends using context and action to carry meaning, keeping dialogue tags simple, and reading dialogue aloud to catch awkward phrasing. Adapted to a letter exchange, those checks can keep each entry clear without overexplaining a character’s intentions. University College Dublin’s creative writing handout
The format can change as you go. If writing long letters feels like too much, try three sentences per turn. If you enjoy the exchange but want more room, add a third round or a short out-of-character note about what each person would like to explore. Either writer can suggest a different premise, a pause, or a finish; the activity works only while both people want to take part.
7. End with a satisfying small finish
After the agreed number of turns, decide together whether the exchange has reached a natural stopping point. You can end with a resolution—a chair is identified, repaired, or put to use—or leave a deliberate small mystery if both of you prefer that. A closing letter can thank the other character, return to an earlier detail, or show how the situation has changed since the first note.
Then check in as friends, outside the fiction: Did you enjoy writing this way? Would you like another round, a different premise, or to stop here? You do not need to turn the exchange into a regular commitment. A short, self-contained correspondence is a complete activity on its own.
