Not every friendship is meant to last forever. But when you know you’re leaving, a few honest words can be kinder than leaving someone to wonder what happened.
Friendships don’t always end because something went wrong. Sometimes life just changes: a new job leaves less time for writing, family takes over, or a correspondence that used to feel easy starts to feel like an obligation you’re keeping up out of habit.
With a pen pal, there’s a very simple way to leave: stop writing. There’s no awkward conversation, no shared social circle to navigate, no chance of running into each other the following week. You can remove a contact, deactivate an account, or just let the last letter go unanswered.
For the person on the other side, though, the ending is rarely that clear. Did you become busy? Did something happen to you? Did they say something wrong? Are you still planning to reply?
Which brings us to the real question: when you already know you’re not coming back, is it kinder to just say so?
Not every quiet friendship is ghosting
Pen pal friendships naturally have pauses.
A person who once wrote every week may start writing once a month. Someone may disappear during exams, a difficult period at work, a house move, or simply a time when they do not have much energy for correspondence.
Sometimes neither person makes a conscious decision to end the friendship. Letters become less frequent until, eventually, they stop.
Friendships can change without ending, too. People become less close, speak less often, or keep certain friendships in a smaller place in their lives. Completely ending a friendship is only one possible outcome. Distancing and redefining the relationship are just as common.
This situation is different when one person has already decided the correspondence is over, while the other is still waiting for the next letter.
Why disappearing can feel easier
Ending a friendship can feel strangely difficult when there has been no argument, betrayal or obvious reason to leave.
If someone has been kind to you, writing “I don’t want to continue this friendship” can feel cruel. Maybe you’re just busy. Maybe you don’t enjoy writing as much as you used to. Maybe you have too many pen pals and need to make room. Maybe you can’t fully explain what changed. In those moments, silence can feel like the gentler option.
There can be real care behind the decision to disappear. In a series of studies published in the Journal of Experimental Psychology: General, people who ghosted others sometimes showed more concern for the other person’s feelings than the person being ghosted realised. Avoiding an explicit rejection could, in some cases, be an attempt to spare someone from being hurt.
The intention can be kind. But what feels gentler to the person leaving doesn’t always feel gentler to the person left behind.
What silence leaves behind
A clear goodbye can be painful, especially if the other person hoped things would continue. But silence creates a different kind of problem: it leaves someone in uncertainty with no clear end point.
Someone who knows a friendship is over can start to make sense of it and move on. Someone who doesn’t know keeps looking for an explanation.
They might reread the last letter they sent, wondering if they asked too many questions, talked too much about themselves, replied too slowly, or wrote something that caused offence. They might consider sending another letter, then worry that sending one would only make things worse.
A 2025 study comparing ghosting with direct rejection found that both caused real distress, but the sting of ghosting faded more slowly. The lack of a clear answer appeared to be an important part of the difference.
A goodbye can’t guarantee closure. The other person may still feel hurt, and may not agree with your decision. What it can offer is clarity. It answers one important question: should I still be waiting for another letter? Sometimes, simply knowing the answer makes all the difference.
Does the friendship really need to end?
Before writing a final letter, it’s worth asking what you actually want to change. Perhaps the friendship itself isn’t the problem. The pace of it might be.
You might still enjoy hearing from your pen pal but can no longer manage long letters every week. You might need a break, or you’d happily keep writing if there were no pressure to reply quickly or match the length of every letter you get.
A friendship doesn’t only have two settings: close or over.
In a Guardian article about ending friendships, counsellors suggest considering whether a friendship really needs to be cut off completely, or whether it could simply take a different form. Friends who were once extremely close may eventually speak only occasionally and still remain part of each other’s lives.
For a pen pal, that might sound like:
“I still enjoy our letters, but I need to write less often,”
“I don’t have much time for correspondence right now, so my replies may take longer.”
Sometimes resetting the expectation is enough to make a friendship enjoyable again, and it’s worth remembering there’s no single universal idea of what a respectful ending looks like.
How comfortable people are with directness, conflict, or ghosting itself varies by culture; a cross-national study spanning twelve countries found real differences in how people understand and use ghosting in both friendships and romantic relationships.
That matters in an international community like Slowly. What feels like an obvious social cue to one person may not be obvious to another. A few clear words can remove some of that uncertainty.
How to say goodbye
If you’ve thought it through and know you genuinely want to stop writing, the next challenge is figuring out what to say. You don’t owe anyone a full account of everything that led to your decision. Sometimes there’s a clear reason worth naming. Perhaps the correspondence has become one-sided, certain topics keep making you uncomfortable, or your expectations no longer match. Other times there’s no real incident at all: circumstances change, enthusiasm changes, a friendship simply stops feeling right. That’s enough on its own.
So how do you put that goodbye into words? A few simple principles can help.
1. Explain simply
If you want to give a reason, plain language usually works better than trying to find the perfect phrase.
You might say:
“I’ve realised that I don’t have the time or energy to keep up with my correspondence anymore.”
“I’ve been reducing the number of people I write to, and unfortunately I don’t think I’ll be able to continue our letters.”
“I’ve appreciated getting to know you, but I feel that it is time for me to step away from this friendship.”
The experts interviewed by The Guardian also caution against relying too much on therapy language when ending a friendship. Carefully chosen phrases can sometimes make a conversation feel more distant or leave the other person unsure what is actually being said. Your goodbye does not need to sound professionally mediated. It should still sound like you.
If getting started is the difficult part, try completing one sentence:
“I’ve been thinking about my correspondence lately, and…”
“I wanted to write rather than disappear because…”
“I’ve really appreciated our letters, but…”
“Before I leave, I wanted to thank you for…”
“I don’t think I’ll be able to continue writing, but I didn’t want to go without saying goodbye.”
Once the first honest sentence is written, the rest often becomes easier.
2. Be clear that you are saying goodbye
There is a difference between being gentle and being vague.
If you know you will not write again, phrases such as “I’ve just been very busy lately” or “perhaps I’ll reply when things settle down” may soften the moment, but they can also leave the other person waiting.
If you genuinely hope to return one day, say so. If you do not, it is kinder not to create a future that you already know is unlikely.
Clarity does not require harshness. A sentence as simple as:
“I don’t think I’ll be able to continue writing, so I wanted to say goodbye properly” can be enough.
The purpose is not to persuade your pen pal that your decision is correct. It is to help them understand what is happening.
3. Acknowledge what the friendship meant
Ending a friendship does not require pretending that it was meaningless.
Perhaps this person helped you through a difficult period. Perhaps you learned about a place or culture you knew almost nothing about. Perhaps their letters regularly made an ordinary day better.
If there is something you appreciated, tell them.
“Thank you for listening to me when I was going through a difficult time.”
“I’ve really enjoyed learning about your life and your country.”
“I’ll remember the conversations we had about books.”
These small details can make an important distinction. “This friendship is ending” does not mean “this friendship never mattered.”
A friendship can have been meaningful and worthwhile even if it does not continue.
When you don’t owe someone a goodbye
There’s an important exception to all of this: a goodbye letter is an act of consideration, not an obligation.
If someone has threatened you, harassed you, repeatedly ignored your boundaries, sent unwanted sexual content, or tried to manipulate or scam you, you don’t need to stay in the conversation to be polite. Leaving immediately is the right call.
Slowly’s own guide to handling upsetting messages is a reminder that you never owe a response to an interaction that’s become harmful or deeply uncomfortable. You can step away, remove the person, and report behaviour that violates the Community Guidelines. Your safety matters more than providing anyone with an explanation.
A friendship can end without having failed
It is easy to judge friendships by how long they last. A friendship of ten years sounds successful. A friendship of six months that ends can feel as though something went wrong.
But duration is only one way of measuring what a relationship gave you.
Someone may have shown up exactly when you needed them. You may have told a pen pal things you found hard to say to people around you. A person on the other side of the world may have made a place feel familiar long before you ever visited it.
Then circumstances change. You change. They change. The correspondence ends. None of that makes the letters you exchanged less real.
If this is the last letter
If you already know that the friendship has come to an end, saying goodbye is unlikely to make the moment painless. But it can spare the other person from being stuck somewhere between friendship and absence, unsure which one they’re actually living in or when it’s time to move on.
You don’t need the perfect final letter. You simply need to tell someone that this is the last one.
Slowly now offers writing prompts to help when you want to send a final letter to a pen pal. They are designed as a starting point, helping you get past the blank page while leaving the goodbye itself in your own words.
